It was a hot one out there this weekend -- and quite a few stars spent it by taking off their clothes.
Rihanna's never met a bikini she didn't show off on Twitter and she shared one of her hottest photos yet while vacationing in St. Tropez.
Wearing a mismatched two-piece, RiRi flaunted her serious curves while enjoying some time on a yacht.
Also showing off her bikini bod was Audrina Patridge, who looked amazing in a barely-there two-piece on Sunday at Foxwoods Resort Casino's Liquid Sundays pool party in Connecticut.
Check out Audrina and Avril Lavigne, who was in Mexico, in the gallery above.
But don't worry ladies (and some men), it's not just the girls who were showing their stuff.
The always sexy Colin Farrell went shirtless at the beach in Cancun, where he put his fit physique and many tattoos on display.
