I should have checked into rehab: Portman

Actress Natalie Portman thinks she should have checked into rehab to recover properly from working on 'Black Swan" instead of starting work on a new film.

The 29-year-old star won a best actress Oscar for her portrayal as a disturbed ballerina in the movie, but admits it was a challenging role, both physically and mentally, she should have taken some proper time out to recover afterwards instead of starting work on Thor, reports a website.

"I loved Darren Aronofsky and working with him was a deeply fulfilling experience but I just showed up for Thor. I probably should have gone into rehab," she said.
