Bradley Cooper packs on the PDA with model girlfriend Irina Shayk

Bradley Cooper's new romance is clearly off to a sizzling start!

The 40-year-old actor packed on the PDA with model girlfriend, Irina Shayk, during a trip to Italy this week, and the photos are hot, hot, hot!

The handsome actor, clad in a set of orange board shorts, passionately leaned in toward his ladylove as they made out on a rocky beach. Shayk, 29, flaunted her equally sexy body in an orange thong bikini, which showed off her pert rear assets and a light blue bikini top. Based on their beachside romp, it's clear the duo can't get enough of each other.

Later the pair were spotted canoodling in a sun chair and Cooper's hands seemed to be roaming all over the Sports Illustrated model's hot bod.

Their sizzling hot snaps showed off their passionate and budding relationship, which reportedly began in May. The spicy couple haven't publicly commented on their romance, but sources say they definitely have great chemistry.

Cooper most recently split from model Suki Waterhouse while Shayk split from her boyfriend of 5 years, Cristiano Ronaldo, in January.
