VIDEO : Irina Shayk Looks Incredible at Cannes Film Festival Just 9 Weeks After Giving Birth

Irana Shayk showed off her post-pregnancy body at the Cannes Film Festival on Tuesday night. The 31-year-old new mom was wearing a shimmering, semi-sheer, curve-hugging dress with a high slit and plunging neckline. Just nine weeks ago Shayk gave birth to her first child with boyfriend Bradley Cooper. 42-year-old Cooper and the Russian supermodel had been dating for two years before welcoming their daughter Lea into the world on March 21. Even in April, less than one month after giving birth, Shayk was already showing off her body in a black bikini on Instagram.
