It was a star-filled day on the beach in St. Barts Tuesday when Julianne Hough and Ryan Seacrest ran into Rachel Zoe, Rodger Berman, and their son Skyler! The group chatted by the water before heading to a nearby house, where they toasted with champagne and snapped pictures on a balcony. Rachel and Rodger have been vacationing on the Caribbean island since before the New Year, while Ryan and Julianne are just getting their holiday started after ringing in 2012 in NYC. Ryan hosted his annual show from Times Square alongside Dick Clark, but he's since switched gears to relaxing with Julianne and friends.
