Robert Pattinson has now made Twihards swoon for five "Twilight Saga" installments as immortal heartthrob Edward Cullen.
But Pattinson, who looked dapper in a forest-green suit at the Los Angeles premiere of "Breaking Dawn - Part 2" Monday night, revealed that he wasn't always so smooth.
"It was terrifying," the 26-year-old actor told E! News, when asked about his first day on the set of 2008's "Twilight."
"I was shooting the last fight scene and I almost ripped my glute. I almost ripped my glute in the first shot I ever did. I was so nervous. I had to have a physio called in and have my butt cheek massaged for the rest of day."
But what's even more awkward to film than fight scenes? Love scenes.
Pattinson recently opened up about his first kiss with Kristen Stewart in "Twilight." "We reshot it twice," Pattinson told MTV News. "I messed it up again. It's hard though. That was a hard scene. That was the audition scene as well. But, it's like in order... I don't know. It's just a difficult one."
