Anna Kendrick told Elle Magazine that despite looking like how she is, no one has hit on her since the film Up in the Air was released.

“I’ve never felt like I’ve exactly traded on my looks. When I was a teenager, I was an ultralate bloomer, and my mom would say it was a blessing, because it means you never have to wonder if guys are only interested in you because you’ve got boobs.  I would have been thrilled if guys were interested in me because of my boobs! Similarly, I think I’m lucky that I’ve never had a crisis about whether the only reason I’m successful is because I’m crazy hot. It’s not something that crosses my mind.”

Maybe it's because of her no-nudity clause in her contracts?
