Irina Shayk is living her best life. Her moment of total (bathing suit) euphoria comes only a few weeks after she and Bradley Cooper welcomed their first child together, a daughter named Lea de Seine Shayk Cooper. The model took to Instagram to share her lounging in her bikini on a giant pool flotation device. Being a new mom has never looked so chic! While Shayk was absorbing some UV rays, Cooper was off filming A Star Is Born with Lady Gaga.
