You know what's got to be awkward?  Having to promote a movie with your co-star, who has just become your ex-boyfriend/girlfriend.  It sounds downright painful.  (Having that movie come in fourth at the box office on opening weekend probably just feels like salt in the wound.)  Just ask Taylor Lautner and Lily Collins, starts of Abduction.  They started dating after they met while working on the movie, and broke up just in time to bring a ton of tension to the red carpet, premieres, after parties, etc.  On the upside, Taylor Lautner is single!  And, he's a very legal 19-years-old, to boot.
