Bradley Cooper, Irina Shayk spotted 'making out' at Rihanna's Met Gala after-party

Actor Bradley Cooper and model Irina Shayk were spotted "making out".

They were seen together at singer Rihanna's Met Gala (an annual fundraising gala for the benefit of the Metropolitan Museum of Art's Costume Institute) after-party on Monday.

The duo stayed at the venue until "three or four in the morning". Sources told the New York Post newspaper's Page Six column that Cooper and Shayk started the night "hanging out in a close group" with Kerry Washington, Leonardo DiCaprio and Tyler Winklevoss, but then slipped downstairs into "the karaoke room", where "they were making out".

"They were very close all night," the source added.

Also at the club dancing in one group, were singers Rihanna, Madonna and supermodel Naomi Campbell. They were later joined by P.Diddy, Miley Cyrus, Jennifer Lawrence and Madonna's 18-year-old daughter Lourdes.

"It was insane. It was a dance-party circle of superstardom," said a source.

Singer Justin Bieber was at the party too and was spotted hanging out with model Kendall Jenner, Gigi and Bella Hadid.
