(Cover) - EN Showbiz - Justin Timberlake is "super cool" to work alongside, according to his co-star.

The actor stars opposite Mila Kunis in romantic comedy Friends with Benefits. The movie follows two friends who decide to embark on a sexual relationship with no strings attached.

Bryan Greenberg also stars in the picture as Mila's character's ex boyfriend. The American actor-and-musician says Justin was a joy to work with.

"I didn't really work too much with him but he was around a lot," he explained in an interview with OK! magazine. "He's super cool and a really nice guy and he's really focused on the acting thing now."

Bryan was humbled working alongside two of Hollywood's hottest stars. The 33-year-old star who is famed for his roles in Bride Wars and The Good Guy says shooting for the film was really enjoyable.

"It was fun. It was Justin and Mila's movie. I had a good time working with Mila. I really liked the script and I thought they were great," he gushed.

"It was a fun project to be involved in."

Bryan is enjoying both his acting and music career at the moment. The star is passionate about being a musician, and doesn't want to chase fame.

"I kind of do both, you know? I'm about to do a little East Coast tour next week. I've always gone back and forth between acting and music, but for music I'm not trying to be a pop star I just like to do it," he admitted. (C) Cover Media
