The 'Valentine's Day' Cast Has Grown So Large (Hi, Joe Jonas!) That We've Diagrammed It Via A Family Tree

With new cast members waltzing onto the set of "Valentine's Day" quicker than Bradley Cooper can swap love interests, we're having a bit of a hard time keeping track of the Hollywood-heavy ensemble cast. We can't be the only ones, so as a public service to all you Crushers out there, here's where the cast list stands thus far (or at least for, you know, the next hour or so):

Julia Roberts, Anne Hathaway, Jessica Alba, Jessica Biel, Jennifer Garner, Shirley MacLaine, Bradley Cooper, Ashton Kutcher, Topher Grace, Emma Roberts, Hector Elizondo, Patrick Dempsey, Eric Dane, Taylor Lautner, Carter Jenkins, Taylor Swift, Jamie Foxx and Queen Latifah. Oh, and let's not forget the newest rumored addition, Joe Jonas.

The casting of Joe alongside ex Taylor (Swift, not Lautner, obvi) got us thinking about other pre-existing relationships at play among the star-studded cast. Because you can't throw that many celebrities together without some drama, am I right? We've put together a nifty "family tree," (see the full-size image after the jump), to break down who's hooked up, who shares DNA and who's been on the same soundstage before. No one can ever say Hollywood Crush isn't educational!

What do you think of our family tree? Did we miss any important relationships? Are you excited to see "Valentine's Day"?
