(Cover) - EN Showbiz - Kellan Lutz "can't not smile" when he watches The Twilight Saga: Breaking Dawn - Part 1 wedding scene.

Kellan plays Emmett Cullen in the Twilight series. Robert Pattinson's character Edward Cullen and Kristen's Stewart's character Bella Swan exchange vows in the newest instalment.

Kellan, whose character Emmett is Edward's brother in the films, found the onscreen matrimony breathtaking.

"Rob looked so handsome and Kristen looked so beautiful... the dress was beautiful." Kellan told Extra. "You feel like you're all one big family and your brother is really tying the knot. You can't not smile."

In reality Kellan gets recognised by fans quite often when he performs his day-to-day duties. He tries to be as natural as possible when dealing with paparazzi.

"You've just gotta live your life. It's tough to just go to the beach because I live so close, and it's like, 'I've gotta keep my shirt on again?'" he explained.

The Twilight Saga: Breaking Dawn - Part 1 will debut in US theatres on November 18. (C) Cover Media
