Beaching while pregnant! Nearly two weeks after Us Weekly exclusively broke news that Hayden Panettiere was expecting her first child, the Nashville star, 24, hit the surf in St. Tropez on Sunday, June 8.

In the French paradise with fiance Wladimir Klitschko, Panettiere debuted the beginning of a baby bump in a flattering black one-piece swimsuit as she swam in the water and chilled out aboard a yacht.

Dating for five years, Panettiere and 6-foot-6 boxer Klitschko, 38, got engaged in 2013, but recently put their wedding on hold because of political unrest in his native Ukraine. The actress has joked about what her kids might look like.

"He's got bowlegs and I've got knocked knees, so they're gonna have straight legs," the five-foot blonde said. "And they'll be normal height!"

"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. "Sometimes people speak about [having kids] like, 'Your life ends—you're never going to be able to do anything again!' And I'm like, 'What are you talking about?' Motherhood is the most beautiful, exciting thing, and there's nothing that I feel like I can't accomplish while having children in my life." See more gorgeous pics of Hayden here.
