IRINA'S LOVE TRIANGE

Bradley Cooper and Tom Brady have both been busy cozying up to supermodel Irina Shayk!

She looked incredible. On Aug. 27, Irina Shayk shared pictures of herself posing atop beachside rock formations wearing nothing but a pair of black string bikini bottoms, socks and hiking shoes. The model, who covered her bare breasts with her hand in the Instagram shots, also posted an eyebrow-raising photo credit the initials LB next to a musical score emoji, hinting at who snapped them: ex Bradley Cooper, who's playing famed composer Leonard Bernstein in Maestro, an upcoming film he also directed and cowrote. Irina more directly confirmed that she and her ex were vacationing together when she posted a sexy shirtless pic of Bradley reclining on a kayak on her Instagram Story.

There's more. Days later, pictures surfaced of Irina and Bradley with their 6-year-old daughter, Lea, looking cozy ahead of the Venice Film Festival. During their Aug. 26 outing - Bradley was in town to check the vision and sound ahead of Maestro's premiere, which he couldn't attend due to the actors' strike - he was seen putting his hands on her back and shoulders and leaning in as they traveled through the romantic Italian city by water taxi and enjoyed an outdoor meal. "Bradley and Irina looked like the perfect couple," says a source. "But there's one problem: Tom Brady."
