Taryn Manning is remorseful for the events that led to her arrest in the early morning hours of last Thursday, according to a source close to the actress.

“She regrets the actions of her night out,” the insider told Celebuzz of the fracas, during which Manning allegedly assaulted good friend and makeup artist Holly Hartman.

According to the source, the 8 Mile star was in New York City for several appearances and to perform DJ gigs; Hartman was tagging along.

What happened between the two that night?

“One thing led to another, and a big night of drinking and being exhausted turned into a regretful scenario,” revealed the source. “It was a personal, stupid fight, and Taryn woke up and found out she did something to her friend.”

“It was like an out-of-body experience.”

According to TMZ, 33-year-old Manning hit Hartman in the face with her fist, kicked her in the face and torso, and slammed her head against the floor and wall. The alleged violence led to Manning being charged with assault and obstruction of breathing or blood circulation.

But Hartman, 23, wants to drop all charges, according to the website.

The alleged incident occurred at the Dream Downtown Hotel, which is no stranger to drama: as Celebuzz previously reported, it’s the same place where Lindsay Lohan was accused of hitting  a pedestrian last month.

Taryn Manning may have taken a different path than her Crossroads co-star Britney Spears, but she still has nothing but kind words for the new X Factor judge.

“I’m really proud of her,” Manning told Celebuzz at The People StyleWatch event in West Hollywood. “I like her suggestions and her critiques [on the show].”

What else did Manning say?

“She really has a lot to say and it’s cool to see her in another light … I’m like, ‘Ooh, Britney! Get ‘em!”

But don’t expect Manning to be making a cameo on her gal pal’s show any time soon. Between American Idol and The Voice, Manning says she “just can’t keep up with them.”

“I feel so far behind,” she confessed. “[They're] all amazing!”

There’s nothing dirrty about Christina Aguilera‘s politics. She just wants you to vote. The chaps wearing singer, new mom and fashion victim headlined a “Rock the Vote” party at the Esquire House in the Hollywood Hills Thursday night.

The event was studded by stars such as Taryn Manning, Rumer Willis, and Kim Kardashian and sister Kourtney.

Kim gave Celebuzz an exclusive quote from the night:

“Last night Kourtney and I hit up Christina Aguilera’s Rock the Vote party at the Esquire house. It’s always good to support a cause you believe in. This is the first time me, Kourtney, Khloe and Rob are even registered to vote. Half of us registered online! It was so easy!”

Kim was able to register without even getting off her butt and you can too, dear reader.
