Justin Bieber and Floyd Mayweather's friendship is well-documented at this point, but the duo has recently moved into a teacher-student relationship as well, with Bieber receiving lessons from the champ in a gym session last month.

Recently, TMZ asked Mayweather if he felt like Bieber has what it take to make the leap from singing into professional boxing, and the always confident Floyd said he was sure of it, adding the "Baby" singer is a "true champion."

The cameraman also asks Mayweather if he thinks the Raiders have a chance to win a game this year, but the Welterweight evades the question, choosing instead to show off the some the stacks of cash he has on hand.
