Some celebrities are bound to heat up the winter season! Check out some of the stars that showed off their winter bikini bodies in 2013 -- including Kim Kardashian, Heidi Montag, Rihanna, and many more.
Debuting her downsize! The Hills alum showed off her bikini body on the beach in Los Angeles on Dec. 1 after she reduced from F to C cups. "I couldn't conceptualize the weight of them in my body," Montag exclusively told Us in the Nov. 18 issue. "They felt like bowling balls on my chest. I felt inappropriate. Guys would stare at me really creepily and felt they had the right to because I had such big boobs."
