Bradley Cooper and Irina Shayk are having a rocky romance. (AKM-GSI)

Bradley Cooper must like Irina Shayk lot — because this pose doesn’t look very comfortable.

The American Sniper star brought the term “summer lovin’” to life when he was photographed making out with his Russian model girlfriend on a pebbled beach on Italy’s Amalfi Coast on Monday. The actor, 40, wore an orange swimsuit and had goggles strapped to his head as he sat by the shore; the Sports Illustrated model, 29, had on a mismatched thong bikini as she draped her body over his.

The smooch photo is already drawing From Here to Eternity comparisons, but there is one major difference — they are lounging on rocks. The Amalfi Coast isn’t known for its long sandy beaches. Rather, they are often patches of pebble, like this.

Clearly, that didn’t matter to these two, who only had eyes for each other.

Cooper has been linked to Shayk since April, one month after he ended a two-year romance with model Suki Waterhouse.

This vacation is a welcome one for the Oscar nominee — in more ways than the obvious one. The busy star ended a 12-week run in The Elephant Man on London’s West End on Saturday.
