Stephanie Seymour showed off multiple bikinis during her recent St. Barts getaway. On Friday she rocked a pink look and later changed into a crocheted one-piece, and on Saturday she hit the beach in a dark string bikini and a printed cover-up. Stephanie's kids Peter, Harry, and Lily were also part of the fun, and the group lounged together on their deck, splashed in the waves, and soaked up the sun. The family's Caribbean vacation is an annual Christmas event, and they aren't the only stars who escaped during the holidays. Rachel Zoe, Jennifer Aniston, and Ellen DeGeneres also traveled to warmer climates to celebrate the season. It's the last chance for bikini fun in 2012, so make sure to check out all the hottest bikini pictures of the year!
