Nashville star Hayden Panettiere flaunted her bikini body at the beach in Miami, Florida, with her fiancé Wladimir Klitschko last Sunday. What made her bikini body stand out was that along with a blue and white striped bikini by Lisa Blue, she was sporting her growing baby bump!

Panettiere, 24, is engaged to Ukrainian heavyweight boxer Klitschko, 38, and they announced in May that they were expecting a baby. Previously, Panettiere had kept her baby bump covered by a one-piece black swimsuit when she went for a dip in June, but she proudly flaunted it while she went to the beach with her fiancé on Sunday.

Panettiere’s bikini had a sweet halter top with gold whale fin charm and a ruffled bottom. The whale fin charm shows her support for the Whaleman Foundation, which makes efforts to protect dolphins and whales, a cause very close to Panettiere’s heart. She wore no makeup and kept her hair in a simple updo, looking like a radiant mother in the sand and sun. Klitschko towered over her and showed off his boxer’s body wearing just neon green swim trunks while helping her dry off after taking a dip in the water.

Klitschko and Panettiere met at a mutual acquaintance’s party in 2009 and dated until 2011, when they parted amicably due to the long-distance nature of the relationship. However, they started dating again in 2013 and announced their engagement in October of the same year.

“I’ve lived a very big life, and I don’t feel my age, and I feel like I was born to be a mother,” she told Glamour in 2013. She’s very excited to have her first child with Klitschko. With season three of Nashville set to begin filming soon, producers of the show have hinted that there is a possibility of Panettiere’s pregnancy being written into the storyline.
