Robert Pattinson celebrated his Best Kiss award at Sunday’s MTV Movie Awards by running into the crowd and smooching his on-screen love rival Taylor Lautner.

Rob and Kristen Stewart – aka Edward Cullen and Bella Swan – scooped the prize for their hot snogging in The Twilight Saga: Eclipse – but Rob decided to leave his girlfriend on stage to accept the gong and give good friend Taylor, 19, a smacker instead.

The male love-in was greeted by screams from the audience, while Kristen, 21, watched on awkwardly.

Eclipse won 4 other Golden Popcorns including Best Movie and Best Fight, and Rob, 25, and Kristen scooped Best Male and Best Female Performance.
