R&B star Ray J has hit back at love rival Bobby Brown over jibes about him in his upcoming book. Ray J has been dating Brown's ex-wife Whitney Houston since the couple split last year and he doesn't appreciate the "My Prerogative" singer calling him a "little man" in his new book.

Although he has nothing personal against his girlfriend's ex-husband, he urges Brown to stop dwelling on the negative about his marriage to Houston.

Ray J tells In Touch magazine, "I think what Bobby's saying in his book is just ridiculous. He should really go back in and pray and figure out what he should do on the positive tip."

And Ray J denies his new song Boyfriend is about his relationship with Houston and his feelings about Brown.

He adds, "I don't want anybody to think I'm taking any shots at Bobby personally and spilling out my relationship or my sex life with Whitney - I would never do nothing like that. I don't kiss and tell, I don't exploit other people's business and I don't think it's cool that Bobby's doing that!"

Of Brown's height jibes, Ray J says, "We're the same height, Bobby, come on!"
