Justin Bieber Reacts To Mom's Playboy Rumors

Last week it was reported that Justin Bieber's mom was offered $50,000 to pose topless in Playboy, and Justin is disgusted at the thought.

"my mom is a moral woman...let's just leave that one for what it is...because that rumor just grossed and wierded me out..." he tweeted on Tuesday.

Pattie Mallete, 34, had Justin when she was 18. Justin is homeschooled (on the road) by a tutor and has a 4.0 GPA despite his weakness in spelling.
