Bryan Greenberg is a singer, songwriter, and actor. Best known for his roles on One Tree Hill, October Road and How to Make it in America and his songs "Someday", "Waiting for Now", and for playing guitar on Will.I.Am's "Yes We Can" song.
Basically, he's legit.
Oh. My. God. I love Bryan Greenberg. It's a shame that he wasted years of his talent on that shitty One Tree Hill show. That shit is FUCKED!
