Searching for Kristen Stewart Smile...

Kristen Stewart is one of the most famous actresses of her generation thanks in no small part to the success of vampire love story Twilight. She should be happy. She's got the looks, the boyfriend every teenage girl dreams of, and the career success. But she isn't happy about it.

The brooding brunette has taken the downbeat glum faces displayed throughout her battle with bloodsucking vampires in Twilight and kept them for her appearances in public. The wannabe diva has also been known to throw a tantrum or two behind the scenes. It wasn't long ago she felt compelled to apologise for comments in Elle magazine that compared the paparazzi to being raped. She also threw a jealous temper tantrum at Megan Fox after seeing her posing for pictures with boyfriend Robert Pattinson.

So is Kristen Stewart a happy bunny. I'm off to find out.
