Adam Levine, who serves as a coach on The Voice, is apparently great at being a jerk.

Actress Keira Knightley did an interview with Glamour magazine for its July 2014 issue in which she discussed what it was like to work with Levine on the set of their new movie Begin Again, Us Weekly reported.

"He did play a dickhead very well," Knightley reportedly said of Levine's acting debut.

In the musical romantic comedy, Knightley plays Levine's character's girlfriend named Greta. Meanwhile, Levine plays a handsome musician who gets overwhelmed by fame and fortune.

"Actually, I admire him being so willing," the 29-year-old actress added, according to Us. "To play a dickhead is quite a big thing when you are trying to break into film and you want to be likable."

Glamour's next issue will be out on June 17. Begin Again will be released in theaters on July 4.

The Voice's seventh season will premiere on Monday, September 22 at 8PM ET/PT on NBC.
