Floyd Mayweather and Justin Bieber can't keep away from each other. The pair attended the NBA match between Los Angeles Clippers and Olkahoma City Thunder together on Sunday night - and even found time to take a few selfies.
Bieber recently led 37-year-old Mayweather into the ring before his fight against Argentina's Marcos Maidana, along with rapper Lil Wayne, and went for a spa with the WBC welterweight champion in the days prior to the big-money bout at the MGM Grand in Las Vegas.
Canadian pop star Bieber might be 17 years younger than Mayweather, but the pair have struck up a real celebrity bond over recent years. Why? Well, we're not quite sure. It's certainly an unlikely friendship: with of the best fighters of all time and a clean-cut pop star. But it's a friendship nonetheless.
What next? Will Mayweather join Bieber at one of his gigs and perform a duet? Will Mayweather adopt his little mate?
