Bradley Cooper and new flame Irina Shayk partied and packed on the PDA after Monday's Met Gala in New York City.

According to the New York Post, the 40-year-old actor and the 29-year-old Russian model, whose romance was unveiled two weeks ago when they were spotted at a Broadway showing of "Finding Neverland," got "hot and heavy" Monday at Rihanna's Met Ball after-party, held at Richie Akiva's Up & Down nightclub.

"[They] were making out . . . they were very close all night," a source told The Post.

Numerous other stars, including Leonardo DiCaprio and Jennifer Lawrence, attended Rihanna's bash.

"It was insane," the insider told The Post. "It was a dance-party circle of superstardom."

Cooper began dating Shayk immediately after breaking up with ex-girlfriend Suki Waterhouse. Sources claim the "American Sniper" star dumped Waterhouse, 25,  because she wasn't appreciative of Cooper's acting skills.

"Cooper felt Waterhouse was not supportive after his huge success in Broadway's 'Elephant Man,'" an insider told Page Six last month. 

"The Elephant Man" ran at the Booth Theater December through February. Cooper has been nominated for a Tony Award for his role in the play, based on the true story of deformed Englishman Joseph Carey Merrick. 

Cooper was out and about in New York again yesterday when iconic restaurant Sardi's unveiled a caricature of the actor that will be display on their walls. 

Cooper will next appear on the big screen in Cameron Crowe's "Aloha," which hits theaters May 29.
