The Sports Illustrated alum looked hotter than ever posing in a sexy black fitted one-piece swimsuit with a plunging neckline, and it's hard to believe that she gave birth just months ago back in April. The new mom showed off her post-baby figure on a boat in St. Tropez adorned with a French flag, hamming it up for the camera in a pinup-inspired updo, bright red lips, and a light knit cardigan. Chrissy Teigen/Snapchat The 30-year-old then got on the other side of the camera and took an adorable shot of Legend—dressed casually for the family's boat excursion in blue shorts, a white T-shirt, and a straw hat—cradling their little daughter in his arms. Chrissy Teigen/Snapchat The 37-year-old crooner later reposted a different angle from their outing on his Instagram account, which he simply captioned, "St. Tropez." The new mom also made time for some special mother-daughter bonding with Luna—on Snapchat, of course. The model shared a video of her and the 3-month-old wearing white towels and trying out the new animal filters, and baby Luna as a tiny dalmatian and giraffe is a whole new level of cuteness.
