The tear-evoking tale, based on the novel by Nicholas Sparks (search), was the favorite drama and date movie among teens.
Gosling and McAdams won for best movie chemistry, and their rain-soaked kiss in the film earned awards for best movie liplock and best movie love scene.
Ashton Kutcher took home three of the awards, including favorite TV actor in a comedy. The perennial teen favorite has won 11 of the awards, more than anyone else.
The awards show, hosted by Rob Schneider and Hilary Duff at the Gibson Amphitheatre in Universal City, will be broadcast at 8 p.m. EDT Tuesday on FOX.
