When ANNE HATHAWAY walked onto the set of "Ocean's 8" for the first time, she was pretty self-conscious, because she still had some baby weight. Luckily, there was enough GIRL POWER in the room to take care of that.

On "Ellen" yesterday (Thurs June 7th), Anne said, quote, "Sandy Bullock looks up and goes, 'You look good mama.' And then Cate Blanchett's like, 'Nice jeans, Hathaway.' And then Rihanna looks up and goes, 'Damn girl, you got an ass.'

"And I of course was freaked out and loved it so much and I go, 'Really?' And she goes, 'You got an ass like me.' And I can honestly say I've never had that experience on a film set before."
