Irina Shayk erased any doubt about her bikini body form with a post on Instagram showing her wading in the ocean in an idyllic scene from her recent tropical vacation. She gave birth just 10 months ago to a baby girl.

Shayk, 31, has been one of the world’s premiere swimsuit models. She’s also appeared several times in Sports Illustrated’s swimsuit issue.

She gave birth March 21 to Daughter Lea De Seine Shayk Cooper. Lea is the first child for the Russian supermodel, 31, and the “Silver Linings Playbook” star Bradley Cooper, 42. They’ve been dating since spring 2015.

Irina wasted no time getting out and about. She was spotted two weeks after giving birth at an L.A. farmer’s market. She was out with her mother Olga Shaykhlislamov.

She was last spotted in public in Santa Monica in December. She and Lea were photographed leaving a “Mommy And Me” class, according to London’s Daily Mail.

Irina did not disclose the location of her super sunny vacation.
