Actress Kristen Stewart, winner of the Best Female Performance award for 'The Twilight Saga: New Moon,' speaks at the 2010 MTV Movie Awards in Los Angeles, June 6, 2010.
In the film, Lautner plays Jacob Black and he is supposed to hate vampire Edward Cullen (Pattinson).
'One of the most challenging things about filming this was having to hate Edward, because I'm looking at Rob (Pattinson) and it was difficult,' aceshowbiz.com quoted Lautner as saying.
'Every time we'd have a shouting match or he'd grab me on the shoulder or something, as soon as they called cut, we'd bust out laughing. Or we'd ruin plenty of takes,' he added.
