The MTV Movie Awards' best kiss honor has been awarded to film couples since 1992, and it has to be our favorite award at the show (OK, maybe aside from best shirtless moment). Whether it's Kristen Stewart and Robert Pattinson's will-they-or-won't-they or the full-on passion between Ryan Gosling and Rachel McAdams, celebrities have accepted their steamy honor in some pretty memorable ways, and it's always one of the most entertaining award-show moments. Before the 21st annual MTV Movie Awards air this weekend, take a trip down memory lane with the best PDA moments from best kiss award winners.
