Natalie Portman needed rehab after Black Swan!

Natalie Portman thinks she should have checked into rehab after filming Black Swan.

The 29-year-old star won a Best Actress Oscar for her portrayal as a disturbed ballerina in the movie, but admits it was such a challenging role, both physically and mentally, she should have taken some proper time out to recover afterward instead of starting work onThor.

She said: “I loved Darren Aronofsky and working with him was a deeply fulfilling experience but I just showed up for Thorspent,” Natalie said.

“I probably should have gone into rehab.”

Natalie who is currently expecting her first child with fiance Benjamin Millepied was thrilled to work with director Kenneth Branagh on Thor because she has always been of his work.

“I must have watched Much Ado About Nothing about 500 times, I love that film so much,” she said.

“He was one of the first people I’ve met that I was excited about when I met them. When I worked with him, it exceeded my expectations.”
