4. Adrian Grenier
Perpetually-bearded star of the douchiest little show in the history of cable TV, Entourage, Grenier was first thrust into the spotlight playing a movie star alongside Kevin Connolly and Jeremy Piven. Since then, however, Grenier's real-life success hasn't exactly mirrored the kind of rising star status his fictional counterpart had. Following the series' last gasps in 2011, Grenier has only played bit parts in a couple of movies that you've likely never seen. Band: The Honey Brothers But that doesn't mean he hasn't been keeping busy. Grenier started drumming in The Honey Brothers, a five-piece jam band with an upbeat indie sound that has the teensiest flairs of Vampire Weekend and Dirty Projectors between the seams. Rather than use his leading man status to play the star in the band, Grenier instead sits behind the kit and is featured sparingly in their music videos, proving that he's not as desperate for attention as some would assume. He also started his own recording studio, Wreckroom, which in turn blossomed naturally into a music label, Wreckroom Records, showing that Grenier has perhaps a more natural knack for behind-the-scenes happenings. Though The Honey Brothers released their last full-length in 2012, that doesn't mean he's done with the band. In fact, their previous album came out six years earlier, which means it wouldn't be outrageous to not see another LP until at least 2018. https://www.youtube.com/watch?v=V-CmMvbCrZY
