Talk about starting 2015 off on a good note. Heidi Klum spent the first few days of the new year with her boyfriend Vito Schnabel in St. Barts, where the 41-year-old model and mother of four showed off her impressive physique. Clad in a tiny brown bikini accessorized with a stack of bracelets and a pair of sunglasses, Klum soaked up the sun with Schnabel.
After ringing in the new year together on the French island, the duo continued to enjoy their vacation waterside, where they spent their time waterskiing and relaxing on a private yacht. But Klum's not the only one who kicked off the new year in a bikini—see all the celebs who have been soaking up the rays in our bikini gallery below!
