News surrounding the third and final installment of the popular Hangover has been slowly building over the past few months as filming quietly kicks off on the upcoming film. Warner Brothers really wants to keep the story as close to the chest as possible for the last chapter in the successful trilogy, but one thing they aren't being tight lipped on is the cast in this film. And that includes the guests making return appearances.

Mike Tyson, Mike Epps, and Ken Jeong will all be returning to previous roles from the series so far, with Jeong said to be making much more of an impact this time around. Now, the first female of the troupe has been confirmed for the final bow and it's sure to create an interesting situation for Ed Helms' Stu.

Variety reports that the latest returning member to be revealed is that of Heather Graham as the sexy pole dancer from Vegas and the first film Jade. Previously attached to the Wolf Pack as Stu's first wife, if you remember the second film then you know Stu eventually married Lauren (Jaime Chung). So could there be a major reunion in store for the former newlyweds and will it affect Stu's current commitment to Lauren?

As of right now, Chung is not currently attached to this project and a storyline could easily occur off-screen. It's hard to predict how Graham's character will fit into the new storyline, but with filming locations revealing that the boys are headed to Tijuana and back to Las Vegas anything is possible. Could it be that the boys are heading back to where it all started for one last weekend with the guys causing Stu to run into his former wife? Or even more important, is Stu still married?

I just have one question for the minds behind the trilogy finale: if Jade is coming back, this means her son will be too, right? Let's just hope that this time the guys won't be carrying a toddler around the City of Sin. Either way, The Hangover: Part III promises to go out with a major bang!

Graham joins returning cast members Bradley Cooper, Zach Galifianakis, Helms, Justin Bartha, Jeong, Tyson, and Epps. Variety's report also promises that the film is "expected to add several well-known actors in cameo roles". Seeing how at one point Mel Gibson was lined up to cameo in the second film only leading to a Liam Neeson replacement, it's safe to say that really anything could happen.

Directed by Todd Phillips, The Hangover: Part III opens in a theater near you on May 24th, 2013.
