Kristen Stewart called herself a “miserable c***” during a recent interview, when she was asked what makes her happy.

“I’m a miserable c***! I’m not sure if I’m most happy when I’m comfortable and content or when I’m pushing myself to the limits,” the Daily Telegraph quoted her as telling Marie Claire in the UK.

“There are such different versions of happy. And I really appreciate both,” she said.

The interview comes after the Twilight star cheated on her co-star and boyfriend Robert Pattinson with married director Rupert Sanders.
