Since what happens in Vegas stays in Vegas, Heather Graham's Jade, the stripper with a heart of gold from "The Hangover," sat things out for the Thailand-set "Hangover Part II." But with the action returning stateside for the comedy franchise's finale, Graham will reprise her role, according to Variety. She'll join Bradley Cooper, Ed Helms, Zach Galifianakis, Mike Epps and Ken Jeong in the Todd Phillips film.

Set for release on May 24, 2013, "The Hangover 3" (or "The Hangover Part III" if they're still feeling fancy) finds Phil, Stu and Alan returning to Las Vegas, as well as making stops in Los Angeles and perhaps Tijuana. Graham's Jade had a brief fling with Helms' Stu in the first "Hangover" film, but her character was jettisoned for "The Hangover Part II," with Stu marrying another woman. Per Variety, expect the pair to share more screen time in the new film.

"The Hangover" series has already grossed over $1 billion in global ticket sales, and made massive stars out of its three leads. Not that everyone is totally pleased with the fame.

"My life was less complicated [before 'The Hangover']," Galifianakis told HuffPost Entertainment. "And not being followed into airport bathrooms by 14 year olds. Nobody would like that."

  • 'Three Amigos'

    The gold standard for comedic trios. This 1986 classic stars Steve Martin, Chevy Chase and Martin Short as silent film actors who portray the fictional Three Amigos. Unfortunately, a woman in danger mistakes them for the real thing and invites them down to Mexico to stop the notorious bandit El Guapo. Things (SPOILER?) work out in the end, but not before the three make complete asses of themselves.

  • 'The Hangover'

    Although the beginning of this movie is less trio and more duo-plus-one, Phil (Bradley Cooper), Stu (Ed Helms) and Allan (Zach Galifianakis) end up coming together to form a rather dynamic -- and completely random -- team who hope to find their missing best friend. They even manage to get a stolen tiger returned to its rightful owner, Mike Tyson.

  • 'The Big Lebowski'

    Pour Donny (Steve Buscemi) may have taken offense to being included on this list. However, before he could voice his complaints, Walter (John Goodman) would have told him to "Shut the f-ck up," while the Dude (Jeff Bridges) would sit there zoned out, daydreaming about bowling. (Clip above NSFW.)

  • 'City Slickers'

    The 1991 comedy starring Billy Crystal, Daniel Stern and Bruno Kirby taught us two things: Under no circumstances should three grown men from the city take a trip to the Southwest to herd cattle, and no matter where a group of best friends travel, they will always find something interesting to talk about.

  • 'Horrible Bosses'

    Some of you may scoff at this 2011 comedy making the list, however, it's hard to argue the chemistry that exists between Jason Bateman, Charlie Day and Jason Sudeikis, who play three friends attempting to murder their overbearing bosses

  • 'Three Men and a Baby'

    In real life, three New York City bachelors taking care of a child that unexpectedly shows up on their doorstep sounds like an absolute disaster. However, in a movie, it's actually a <em>fun</em> disaster! (Also, there's nothing more entertaining than watching the mustachioed Tom Selleck struggle to change a baby's diaper.)

  • 'Airheads'

    In "Airheads," Adam Sandler, Brendan Fraser and Steve Buscemi play wannabe rock stars who break into a radio station to get their record on the air. Then, one thing leads to another and they end up taking everyone inside the building hostage using plastic water guns.

  • 'Old School'

    Frank the Tank! Frank the Tank! The second Todd Philips film on our list -- and the aughts favorite frat comedy -- starred Will Ferrell, Luke Wilson and Vince Vaughn as three middle-aged buddies who end up starting a fraternity after one of them moves into a giant house on campus. There's jello wrestling, streaking and, of course, Snoop Dogg. (Clip above NSFW.)

  • 'Ferris Bueller's Day Off'

    You may think that this movie was just a one-man show, however, Ferris Bueller (Matthew Broderick) wouldn't have had that awesome day of fun without his sidekick Cameron (Alan Ruck) and his girlfriend Sloane (Mia Sara). See how well they complement each other during this Sausage King of Chicago restaurant scene?

  • 'Triplets'

    Haha, just kidding. <a href="http://www.huffingtonpost.com/2012/03/29/twins-sequel-triplets_n_1390076.html?ref=moviefone&ir=Moviefone" target="_hplink">If this thing gets made</a>, stay far, far away.
