Floyd Mayweather was joined by a couple of hip hop superstars and a pop prince to celebrate his victory in the ring over Cotto on Saturday.
The Biebs had nothing but praise for the undefeated champ. "He's the best boxer in the world," he told V magazine. "When everyone else just chills and doesn't work out because they are not fighting, he's in there punching the bags because he wants to be the best. He wants to be better than Muhammad Ali, and that's what he's striving to be."
The "Boyfriend" singer says that he partakes in a little boxing himself. "Me and my friends box all the time," he said. "My dad is a fighter so he taught me some stuff growing up, and he's a great fighter, so I'm a pretty good boxer."
