Robert Pattinson Recalls 'Butt Cheek' Massage During First Day Of 'Twilight' Filming

Leave it to Robert Pattinson to somehow work in the phrase "massage my butt cheek" into a recollection of all things "Twilight" during the junket for the film franchise's finale, "Breaking Dawn - Part 2."

You see, MTV News' Josh Horowitz wanted to spend a pleasant moment hearkening back to the very beginnings of the saga, and thusly asked Rob what he remembered from that first day of filming "Twilight."

"We were doing the fight scene at the end of the first one, and I tore my glute, well, almost tore it, basically in my second shot of the whole movie—of the whole series," the actor explained. "[They] had to get a physiotherapist to come in and massage my butt cheek for the rest of the day." (Hard job!)

As for the lesson learned from his tushie trouble, Rob wasn't so sure. "That was the most prep I've ever put into a movie," he said. "I was there for three months working out and stuff. I was at my peek, physical prime, and then...ass done. The ass is out!"

"The Twilight Saga: Breaking Dawn - Part 2" hits theaters November 16.

So...considering a career as a physiotherapist?
