Steamy smooch! Bradley Cooper received a friendly visit from girlfriend Suki Waterhouse (and then some!) on set of his upcoming film American Sniper in L.A. on Wednesday, June 4.

Cooper, 39 and the model, 22, were photographed making out on the beach while the actor was dressed in a camouflage uniform. In the intimate moment, Waterhouse leaned in for a big kiss as she wrapped her arms around his waist. (A day earlier, Cooper, who stars in the flick with Sienna Miller, donned incredibly tight short-shorts while filming.)

Last January, the young Brit opened up briefly about the actor during an interview with ELLE UK. "I don't talk about my boyfriend because it's boring," Waterhouse said.

When asked about starting a family, she replied: "I really like the idea of having kids in not too long. Not, like, now. And not next year. But in not too long."

The hunky actor and Waterhouse were last spotted brushing shoulders at the the Metropolitan Museum of Art's Costume Institute Gala in NYC last month. A scruffy Cooper wore a sleek three-piece tuxedo while Waterhouse trailed behind in a layered Burberry gown. Despite the public appearance, the twosome took no photographs together on the red carpet.
