One guy who seems to be heading in a bigger recurring role in the series is Sam Evans which is wonderfully played by actor Chord Overstreet. You may have heard his name already as he is a friend of Demi Lovato (Camp Rock) and has landed roles in ICarly.
Blonde and big mouth (as in literally taken), but Chord is definitely an addition to the cast. He has the looks that is somehow a mixture of Justin Bieber and Macaulay Culkin. And aside from that he has the voice. His Billionaire version with the rest of the guys was a-hot. That song was never easy to cover. And I know his locker room/shower scene also poked your interest. For more on him watch the Season 2 of Glee.
