If you watched Floyd Mayweather Jr.'s victory over Miguel Cotto last night, chances are you noticed he had a high-profile escort walk with him to the ring. It was Justin Bieber, whose connection to boxing continues to grow after we had him get "knocked around" for his Complex cover. You probably also noticed that the "Boyfriend" singer celebrated Mayweather's win by holding up his belts and then posed for pictures with the boxer and his other musical pals, 50 Cent and Lil Wayne. You can check out those photos above and peep Mayweather's tweet at Bieber below.
