Zap2it caught up with Pettyfer at a round table promoting CBS Films’ “Beastly” where he told us that he’s taking a cue from his “Stormbreaker” costar, Ewan Mc Gregor.
“Keep your personal life personal,” he says of the advice Mc Gregor once gave him.
The actor in 2009, and her single "Back to December" is rumored to about the relationship; Gomez dated him earlier that same year.
C'est alors qu'elle apparaît dans plusieurs séries télévisées telles que Les Experts : Manhattan, Close to Home : Juste Cause ou Numbers et obtient un rôle dans Veronica Mars.
Elle joue également Debbie Marshall, aux côtés d'Hayden Panettiere dans Heroes en 2007.
Love on the set may seem like a good idea at the time, but when the film hits theaters and the romance fizzles — maybe they’ll think twice on the next set. The couple, who met while filming “I Am Number Four,” are reportedly on less than friendly terms with Us Magazine even claiming that the “Glee” babe is “terrified” of her ex.
While reps for the actors have obviously remained mum on the situation, don’t expect Pettyfer to pipe up anytime soon either.
“Keep your work separate.” Let’s just say we aren’t expecting him to shack up with fellow newly single “Beastly” co-star, Vamessa Hudgens anytime soon.
