The Harry Potter and the Deathly Hallows actress turns 46 on Saturday (May 26) and we have no doubt she’ll be celebrating with her beau — and often onscreen collaborator — Tim Burton, son Billy, 8, and daughter Nell, 5, in gothic-chic style.

To ring in her big birthday, Celebuzz is taking a look at Helena’s many head-turning styles. From big hair to even bigger ball gowns, click through the gallery to see Helena’s most outrageous looks through the years!

This year, we saw plenty of fashion from Helena as she strutted her stuff for Dark Shadows premieres across the globe. Check out her red carpet garb — and why she nearly didn’t get cast in the film — in the video below!

This week, celebs were dressed to the nines as they stepped out for premieres and red carpet events coast to coast.

“Over the years, we have enjoyed … any number of what we call films – and you might call movies,” the Queen told her guests, according to People.com. “[The] exchange of people and projects has enlarged and invigorated our common language – although I think you will agree we don’t always use it in quite the same way.”

Look out for Helena in Harry Potter and the Deathly Hallows: Part 2 where she plays Bellatrix Lestrange.

Mia Wasikowska—who plays the title character in the sure-to-be-mindbending retelling of Lewis Carroll‘s surreal classic—prettied up the event, along with her co-stars Johnny Depp, Anne Hathaway and Helena Bonham Carter.

Go ahead and take a leap down the rabbit hole by clicking through our photo gallery.

A little bit of Johnny Depp as the Mad Hatter would have been nice, but all in due time, we suppose…

Check out the clip and sound off in the comments section: Do you think Burton can pull off Alice in Wonderland, or do we have another Planet of the Apes on our hands?

The trailer for Tim Burton‘s upcoming re-envisioning of the Lewis Carroll classic Alice in Wonderland has been released.

Hathaway will be playing the White Queen. The cast also includes mega-bucks actor Johnny Depp, who’ll play the Mad Hatter, and Burton’s longtime companion and fellow fashion renegade, Helena Bonham Carter.

Congratulations, Anne! With your recent experiences, you shouldn’t have any trouble stealing the show.

Or rather, Tim was walking. Helena was pogo-ing on her Z Coil shoes. Who knows—maybe the English thespian is suffering from foot pain?

Or perhaps she and Burton just get up to some freaky jazz, and she forgot to take off all the naughtywear before leaving the house.

Anyway, the black-clad couple were on

their way to pick up their son Billy Ray from school. That kid just oughtta be happy mom and dad didn’t look like this again.

It must have been a rough morning for Helena, who hit the town in what looked like a fright wig and pants made seemingly from IKEA curtains.

Of course, there are always worse ways for a parent to dress.

Luckily the bizarrely-outfitted couple got their acts together enough to prepare the children for a rainy London day. Still, they should try to remember to leave the costumes to the to the kiddies.

Since stars, much like normal people, tend not to appreciate it when strangers come up and sniff them, we’ll have to judge by looks and reputation alone.

Sure, calling people stinkers is petty and superficial, but we’re dealing with a shallow business in a shallow world.
