Bradley Cooper and Irina Shayk 'making out' at Rihanna’s private Met Ball afterparty

Bradley Cooper and Irina Shayk grew "very close" at a Met Ball afterparty, according to the New York Post's Page Six.

Elephant Man actor, Cooper, 40 – who recently split from Suki Waterhouse – was reportedly“making out” with Russian model Shayk, 29, at Rihanna’s private after party at Richie Akiva’s Up & Down nightclub until “3 or 4 in the morning” according to a source.

The pair – who were spotted "hanging out in a close group" with Leonardo DiCaprio, Kerry Washington and Tyler Winklevoss – later slipped downstairs into “the karaoke room,” after getting "very close all night”.

The Sports Illustrated swimsuit model – who dated footballer Cristiano Ronaldo for five years – was first spotted with the American Sniper actor as they watched the Broadway production of Finding Neverland. They later attended the White House Correspondents’ dinner last month.

Other attendees at Rihanna's "insane" afterparty included Madonna and her daughter Lourdes, singer Selena Gomez and her ex-boyfriend Justin Bieber, and Balmain's Olivier Rousteing.

A souce said: “Diddy got in there, Miley [Cyrus] got in there, then Jennifer Lawrence. It was insane. It was a dance-party circle of superstardom.”
