Kourtney Kardashian showed off her post-baby body in Miami after giving birth to her daughter, Penelope, only a year ago. The Keeping Up with the Kardashians star, 34, relaxed by the pool in a one-piece swimsuit with her two kids; Mason, 3, and Penelope, 1, and her longtime boyfriend Scott Disick.

The mom of two shared pictures on her Instagram account, one in a black one-piece with Disick and another in a bright yellow strapless bathing suit with former Real Housewives of Miami star Larsa Pippen, the wife of NBA star Scottie Pippen.

Kourtney talked to Us Weekly about losing her baby weight the second time. “It was harder to lose weight the second time around," she said. "I gained 45 pounds with Penelope."

She added "This time, the focus is really on being a mom and being present, knowing my priorities.”

Meanwhile, Kourtney’s sister Kim Kardashian, who gave birth to baby North West on June 15 and hasn’t been photographed since before then, is still working on losing her baby weight.

The Hollywood Gossip reports that she’s looking up to Beyonce for inspiration for losing the pregnancy pounds, and she’s already lost 20 pounds from breast feeding.
