Justin Bieber is friends with boxing legend Floyd Mayweather, Jr.

So, if Orlando Bloom is planning to continue his “feud” with Bieber, he might want to listen to the advice of former UFC light heavyweight champion Forrest Griffin.

Bloom and Bieber were recently involved in an “alleged” altercation at a restaurant. While Bieber can acquire the services of “Money” to help with his offense, Griffin is offering his services to Bloom.

“He threw a weak-ass punch,” said Griffin, in an interview with TMZ. “I gotta warn Orland. I think Floyd is gonna train Bieber, and that guy’s a monster.”

Bieber has continued the feud, posting a picture of a crying Bloom on his Twitter account.
