Don't believe rumors about Floyd Mayweather Jr. and that teenage girl

The rumor started last weekend: Floyd Mayweather Jr. is dating a 19-year-old shop girl from London.

She'd been posting pics with Mayweather on Instagram for the past few weeks, and the gossip sites reported that the 39-year-old boxing star was traveling around the world with her to sweep her off her feet.

Not true, according to Mayweather's reps, who told TMZ that his interest in the young woman, Raemarni Ball, is strictly professional —€” she's a singer and he's looking to manage her music career.

Though judging by the skills she's showed on Instagram, Mayweather may want to get back in the gym.
