Bradley Cooper and girlfriend Irina Shayk just had a vacation in the Bahamas last month, but now it's back to work for the Sports Illustrated model as she graces LOVE magazine's advent calendar in a sexy one-piece.

A video of the campaign was published by Daily Mail, showing just why the "American Sniper" actor is so enamored with his girflriend.

"The 29-year-old girlfriend of Bradley Cooper hit a New York beach wearing a pair of very small denim hotpants, which she peels off to reveal a sexy plunging one-piece," Daily Mail reported. "Sashaying to the tune of Beach Boys' song, Merry Christmas, Baby, the brunette beauty reclines on a floral deck chair and lathers her body in sun lotion, despite the lack of sun,"

Ever since they went public with their relationship, Bradley Cooper and girlfriend Irina Shayk have been nearly inseparable.

Just last month, Bradley Cooper's girlfriend again displayed her model body while on vacation with the actor in the Bahamas.

"Irina showed off her world famous figure in a black bikini, as she relaxed back onboard the boat - at one point revealing her toned bum in the barely-there bottoms," UK's Mirror said.

"Stripping down to tiny swimwear, the pair were snapped laughing together as their PDA-filled afternoon the next day descended into a full blown water fight," the article added.

In August, they soaked in the sights in Italy and hit the beach in the Amalfi Coast, but multiple photos of their vacation showed that the pair was more interested in each other.

According to OK! Magazine, as shared by Celebrity Dirty Laundry, Bradley Cooper and girlfriend Irina Shayk are already house-hunting together in New York, which it took to mean that they are already planning a wedding.

"Things are moving really quickly for them. Bradley told Irina he loves her and asked her to move in with him, and she didn't hesitate to say yes," the source alleged.
