Other Details: Anna Faris and Chris Evans have come a long way since their days of starring in parodies of late-90s movies (Scary Movie, Not Another Teen Movie). After all, Anna Faris is now a blond and letting her lips discover the wonders of Juvederm and Chris Evans shaved his sideburns and became a hot superhero. But seriously, now they're both legit marquee names and co-stars in the upcoming What's Your Number? which premiered last night in Westwood. The two were backed by their fellow cast and crew at the big night celebrating the film that deals with the burning question we all will probably ask ourselves at some point: "am I a slut??"
