In 2010, the 27-year-old had listed the estate — located in the gated neighborhood Bowmont Estates in Beverly Glen, Calif. — for $8.695 million, but she received no offers.

According to the listing, the 7,607 square foot home has eight bedrooms, with four of which are attached to en suite bathrooms.

The listing also adds that the living, dining and family rooms are furnished with a working fireplaces with “spectacular canyon and Catalina views.”

Justin Bieber received major criticism for sporting overalls when receiving the Diamond Jubilee Medal from Canadian Prime Minister Stephen Harper during Thanksgiving weekend — but he surprisingly wasn’t the first celeb to have sported this fashion flashback trend.

Tons of A-listers have opted for overalls as their style statement of choice — including “Diamonds” songstress Rihanna, Project Runway‘s Heidi Klum, and former OC star Mischa Barton.

Bad Teacher actress Cameron Diaz, 40, traded in her signature structured ensembles for a suspenders-and-skirt combo in New York City. Donning a form-fitted white tee under her mini denim piece, the blonde beauty still looked flirty — sprucing up her ensemble with bold bangles and a tan shoulder purse.

British style icon Alexa Chung has also been spotted out and about in a denim one-piece — looking hippie chic in her loose floral blouse and trendy flared overalls when she recently made her mark in Sydney, Australia.

The star-studded streets have proven that with so many variations, overalls can easily fit into one’s wardrobe.

Harper even jumped to defend Bieber’s overalls, writing on Saturday: “In fairness to @justinbieber, I told him I would be wearing my overalls too.”

Black is back if the latest snaps of Hollywood stars are anything to go by.

Despite the Miami heat Britney Spears, 30, and her fiance, Jason Trawick, 40 donned dark attire as they they left their hotel in the ‘Sunshine State’.

Luckily the new X-Factor USA judge’s hot pants and sequinned vest ensemble still exposed plenty of skin.

Who else turned to the dark side?

Looks like former O.C beauty Mischa Barton, 26, is making England her home.

Wearing a floaty black dress and heels the 26-year-old launched her flagship clothing boutique – fittingly named Mischa Barton – in London’s trendy Spitalfields Market.

Actor Sly Stallone, 66, hid behind dark shades and wore a black polo shirt as he arrived at his hotel in Paris, France.

The star is enjoying some family time away with his wife, Jennifer Flavin and three daughters, Sophia Rose, 15, Sistine Rose, 14 and Scarlet Rose, 10 as they mourn the loss of Stallone’s son Sage.

And Gavin Rossdale, 46, wore black board shorts and nothing else as he taught his adorable son, Kingston, to boogie board in Florida.

She’s pretty in pink and head-over-heels for her new man.

Mischa Barton was spotted getting hot and heavy with beau Sebastian Knapp on the beaches of Formentera, Spain on Friday.

Sporting a hot pink swimsuit, the 26-year-old ventured out into the water solo before packing on serious PDA with Knapp.

So who is Barton’s new guy?

Knapp is a London-based actor who’s appeared in films such as 28 Days Later and One Point O.

The couple reportedly started dating just one month ago, and recently went public after been seen clubbing in London.

A few months ago, Mischa Barton, 26, was spotted running around the streets of Los Angeles in leopard-printed underwear, all for the music video for Noel Gallagher’s new single, ‘Everybody’s On the Run.’

Well, at long last, the finished product has been released!

So, what exactly happened to Barton’s clothes?

In the video, which you can check out above, the former star of The O.C. gets her dress caught in the door of a cab that Gallagher is driving. When Gallagher speeds off, the shocked starlet starts running after him through the streets, even though she is, you know, down to her underwear.

Meanwhile, as Barton finds herself chasing after her clothes, so does a man standing outside a hotel, after his shoes are lifted by a skateboarder.

Taking a cue from Barton, the unnamed man chases after his shoes. To his utter surprise (not to mention luck), he winds up falling in love with the actress after they bump into each other.

Apparently, losing clothes leads to finding true love!

Mischa Barton is all about skin lately!

The 26-year-old star was seen attending the Women For Women International Gala in London on Thursday, and showed off some side boob in a white dress. In addition to that, The O.C. star flaunted a bit of abs, as there were side cut outs on her ensemble.

Just recently, Mischa was spotted running around the streets in her underwear!

But she was shooting a music video, so don’t be too alarmed.

Mischa isn’t the only advocate for side boob. Miley Cyrus is a big fan of the scantily trend too, as she was seen braless while shopping just a couple of weeks ago.

Mischa Barton gave everyone quite an eyeful when she decided to strip down to her underwear while shooting a music video on Monday.

Wearing just a leopard print bra and underwear, the 26-year-old actress showed off her slim figure and midriff as she and a male co-star filmed Noel Gallagher of Oasis’ video on the busy streets of downtown Los Angeles. Between takes, she was all smiles — and didn’t seem to mind all the eyes ogling her nearly naked bod.

The former OC actress has never been shy about her outrageous fashion sense.

First, Elizabeth Olsen went retro this week. Now, Mischa Barton has done the same.

The former OC actress looked right out of the 1960s Monday night in Hollywood, CA, donning a see-through (yes, see-through) polka dot top, black leather pants and ponytail.

It was a bold look for Mischa, and we appreciate the effort. Still, we’re not sure if it actually worked. (Seriously, see-through?)

Mischa is celebrating her b-day today, but her OC actress Rachel Bilson is taking little digs at her costar. 

During the filming of a silly Funny Or Die music video in promotion of her new show Hart of Dixie, Rachel called out Mischa for not doing much since their hit FOX show went off the air. The petite actress rapped, “Did a couple movies, drank a couple juices!/ Still they comin’ at me, like ‘Where ya been?’/ You should be askin’ Mischa Barton!” Ouch! 

Who was your fave OC star: Mischa or Rachel? 

This OC star headed down to the East Coast to catch some rays. Mischa Barton was spotted not once, but twice in teeny bikinis on Miami Beach, most recently on the first Monday of 2012, Jan. 2.

Mischa Barton sure isn’t afraid to show a little skin. The OC actress lounged by the pool and showed off her slim figure as she soaked up a few rays in Miami on Tuesday afternoon.

Mischa wore a teeny black bikini, paired with white sunglasses as she relaxed with a male companion. The two chatted and even snapped a few photos of the gorgeous blue ocean.

Of course, Mischa isn’t the only sexy celeb stepping out in a bikini. A few days ago, LeAnn Rimes sported a white bikini while on vacation in Cabo San Lucas with Eddie Cibrian. She flaunted her figure and by the looks of these pics, could barely keep her hands off of her hubby!

Mischa Barton rarely makes public appearances these days, but on Tuesday night, The OC actress made an acception and stepped out in yet another edgy style. 

The fashionista showed up at the G-Star Rodeo Drive opening event wearing a velvet blazer with fuzzy embellishments on the shoulders. She paired the peculiar outerwear on with black slacks, a fitted black blouse and a Chanel purse. We’re kind of liking this look but what do you think: Yay or Nay on the fuzzy shoulders?

When you take style risks like Mischa’s does, the outfits don’t always land you on the Best Dressed lists. Here at Celebuzz, we frequently find her ensembles questionable, including this colonial look she wore back in August while at Hollywood hotspot Chateau Marmont.

While controversy surrounds Tyler Shields‘ photo shoot with Glee gal Heather Morris and her black eye, that didn’t stop the celebrity photographer from posting pics of Mischa Barton gnawing on raw meat!

The former OC star posed in a series of shots with the raw steak, with her red lipstick on full display. Tyler wrote about the shoot: 

So one day out of the blue I start getting emails with the subject ‘Mischa Barton.’ Upon opening the emails I realize they are from her fan club in Brazil. They were asking me to shoot her. … At the same time they were emailing me, they were emailing one of her best friends about me. I randomly met her friend and we talked about it. A few days later, this happened …  She was amazing to work with and I cant wait to do it again.”

Meanwhile, upon releasing the Heather Morris shots, Shields received “death threats” over the shots that showed Heather bruised. “It was 25,000, maybe more,” he told the LA Times, “of the most violent, insane things.”

“This wasn’t glorifying domestic violence,” Tyler continued. “I didn’t sit down and say, ‘It would be awesome to punch the girl from Glee in the face.’ She’s clearly in makeup and doing Barbie gone nuts.”

What do you think of Tyler’s photographs? Are they too shocking or is that the point of art? Sound off in the comments!

We haven’t seen Mischa in a while and perhaps it’s because she’s always cast on celebrity worst dressed lists.

After an extended absence from the celebrity scene, Mischa Barton is back with a new, albeit bizarre, look. The former OC star was spotted wearing a pair of red, Carrie Donovan-esque glasses when she left the south of France on Friday.

Mischa paired the outrageous red plastic glasses with a striped red and white sweatshirt and tight red pants. The young actress has made quite a name for herself for her unique sense of fashion – she nearly gave the internet a heart attack when she stepped out in “yellow banana pants” in 2010 and her hipster-ish style has always been a talking point.
