Justin Combs received a lesson on ignoring the haters yesterday from his “big bro,” R&B singer Tyrese. As most of us know, Justin’s father Diddy allegedly assaulted his UCLA strengthening coach, resulting in him getting arrested on a slew of charges. Reports say Sean Combs confronted Sal Alosi after he was seen “riding Justin, screaming intensely at him” during the football practice. According to Tyrese, Alosi seemed to be attacking Justin because of his father’s celebrity. “There IS A such thing as people purposely treating YOU like s*** because of WHO your dad IS,” he wrote in his public letter to “UCLA’s young KING.”
