Trey Songz is known for getting sexy with fans while on stage, but his last performance was one to remember. He brought a fan on stage, sang to her a little, then he started unbuttoning his shirt per usual. The singer grabs the fan and picks her up while dancing. Then….. he just gets up and walk away with her! Who knows what happened after that but we all know the girl on stage has one heck of a story to tell!
