Zac Efron Embarrassed By 'The Lucky One' Sex Scenes

In The Lucky One, opening today, things get pretty hot and steamy between Zac Efron, 24, and Taylor Schilling. At a Thursday screening of the film in New York City, however, Efron was not patting himself on the back — he was looking for the exit sign.

Why? Because Efron's mom, Starla, was in the audience. "We saw the film together and I was kind of squirming," Efron told People. "Even though she was a couple of seats down from me, I tried to duck out during those scenes because it was too embarrassing. Obviously I'm acting, but knowing that my mom and my family were watching is kind of awkward. There's really no way around it."
