The Sports Illustrated model's boobs almost popped out of her top as she danced around with co-stars Cameron Diaz and Leslie Mann in West Hampton, New York.
Kate's pretty white camisole had been undone almost to her belly button and her bright yellow bra was on display.
The Other Woman - which is due to be released next year - is a comedy movie which tells the story of a woman who realises she's not her boyfriend's only lover.
She teams up with his wife so they can get their revenge on the cheat, played by Game Of Thrones star Nikolaj Coster-Waldau.
Kate, 21, is known for her ample chest and has previously said that she 'loves' her body.
'I can't change my bra size. They're natural! I can work out and I can stay healthy and motivated, but I can't change some things,' Kate told US Vogue last month.
'It's what God gave me! I feel confident with myself, and if that inspires other women to feel confident with their bodies, great.'
