AceShowbiz - Anne Hathaway was showered with compliments on the set of "Ocean's 8" not long after she gave birth to her son.

The actress and her husband Adam Shulman welcomed their tot Jonathan in March 2016, and later that year she began filming the all-female instalment of the heist film series.

While she was conscious of still carrying some baby weight, her co-stars made her feel fantastic when the shoot began.

"It was really significant to me because it was my first movie after having my son," she told Ellen DeGeneres during an appearance on her show.

"I walked on the set and my weight's a little up and I'm just aware of it. And I walk onto set, and I'm in my jeans and I've done my best and I'm going to love myself no matter what and Sandy Bullock just looks up and goes, 'Looking good mama.' And I was like, 'Oof that made me feel amazing.' And then Cate Blanchett's like, 'Nice jeans Hathaway.' This is so great! And then Rihanna looks up and goes, 'Damn girl, you got an a*s.' And I of course was freaked out and loved it so much and go, 'Really?' And she goes, 'You got an a*s like me.' And I can honestly say I've never had that experience on a film set before."

The 35-year-old went on to reveal the shoot was a "real love fest". And it wasn't just the A-list cast that made Anne feel at ease, but director and writer Gary Ross too.

"One of the lucky things about being in this business for so long is that I've really come to terms with the pressure that you get to look a certain way as an actress, and I don't beat myself up about that stuff anymore," Anne confessed. "But after I had my son the weight was really slow to come off, so I was a different size to what I normally am and the director told me, 'That's great, we have eight women in this movie, we need to have as many body types up there as we can.' Which I was really relieved to hear."

Ocean's 8, which also stars Mindy Kaling, Sarah Paulson, Helena Bonham Carter and Awkwafina, hits cinemas from Thursday, June 07.
