And the Wolfpack is back and returning to Las Vegas! The stars of "The Hangover III" gathered at the Westwood Village theatre in Los Angeles for the premiere of their new film.

Stars Bradley Cooper, Ed Helms, Zach Galifianakis, Ken Jeong, Heatehr Graham, and Justin Bartha were all there to celebrate the end of Todd Phillip's tale of debauchery, according to Moviefone.

For their red carpet looks both Helms and Galifianakis decided to go with classic suit jackets and ties, however Bradley Cooper sported a copper suit that look like he could have took it from the wardrobe department of his upcoming 1970's period film "American Hustle."

While the men of the film stuck to their version of appropriate suits, the females of the brood decided to make fashion statements.

Heather Graham wore a low-cut emerald Green gown that she paired with an oversized necklace. Jamie Chung also rocked a low-cut gown but this one was a tad more revealing than Graham's dress. She sported a long black lace gown which only had a thin piece of fabric keep the actress' bust from being exposed.

Zach Galifianakis was spotted with a date who was not his wife of almost one year, Quinn Lundberg. Instead he was seen with a former homeless friend of his, Elizabeth "Mimi" Haist. According to the Daily News, the actor has been friends with Haist for almost 20 years.

Galifianakis met Haist back in 1994 at Fox Laundry when he was first starting out in Hollywood. At the time Haist volunteered at the laundromat and survived on tips given to her by customers.

Once he shot to fame Galifianakis stopped going to the laundromat but two years ago, when the actor learned his old friend had become homeless he tracked her down.

When he found her, he set her up in a one bedroom apartment that he pays rent and utilities for. The actor reached out to Renee Zellweger who outfitted the apartment with furniture and makes sure her fridge is always stocked.

For fans who were ever curious about who the older woman who is ocassionally seen hanging off of the arm of Zach Galifianakis, it is Haist. She has accompanied the actor a number of times to his movie premieres and is enjoying her time in the Hollywood light.

"It's fun, not something I've ever dreamed I'd experience."
