It's that time of year again! Hollywood's biggest stars have been escaping the frigid winter weather and heading to the sandy beaches of tropical destinations—like Mexico, Miami Beach, and Hawaii—for some much needed down-time and of course, to show off their hard-earned bikini bodies. As Demi Moore and her family enjoyed a trip to Mexico, Jennifer Aniston and fiancé Justin Theroux headed to Los Cabos (one of their favorite winter destinations!) with a few of their close friends, while Bethenny Frankel and Katie Holmes headed to sunny Miami Beach. Transport yourself to the same beaches by looking through our gallery to see more bikini-clad celebrities.
