How are famous people on you tube like Tim Delaghetto, Davedays, KevJumba, and Nigahiga getting really famous people in Hollywood to be in their videos? I noticed this first with Davedays and Miley Cyrus, then NigaHiga with Quest Crew, Kevjumba with so Real Cru, and then Tim Delaghetto with the actor from The Blind Side - Quinton Aaron.
Damn they can't be paying these people to come in their videos, so then is this just for publicity purposes? Like individual actors, singers, dancers call up their favorite you tube stars and ask them to be in their videos?

If that's the case...I wonder whose coming on you tube next.
