Floyd Mayweather Jr. romancing 19-year-old aspiring singer

MIAMI, March 16 (UPI) -- Floyd Mayweather, Jr.'s romance with a 19-year-old aspiring singer appears to be going strong.

The 39-year-old retired boxer cozied up to Raemarni Ball, aka Rmarni, in new photos the British teenager shared this week on Instagram.

"His funky hat is quite cool @floydmayweather," she captioned one snapshot.

Mayweather and Rmarni were vacationing in Miami after meeting last month on the boxer's U.K. tour. The aspiring singer reportedly paid over $800 for a ticket to Mayweather's show in Cannock, England.

The rumored couple went public with their relationship at the Los Angeles Clippers and Golden State Warriors basketball game in February. Mayweather whisked Rmarni away on his private jet and the teenager later shared a clip of Beyonce at the game.

Rmarni is an aspiring singer who posted a first track to SoundCloud in November. The teenager has rubbed shoulders with Rita Ora and Jhene Aiko and is often spotted in clothing from Mayweather's lifestyle brand, The Money Team.

Mayweather retired from the ring in September as an undefeated professional boxer. The five-division world champion won 12 world titles and generated more than $1.3 billion in pay-per-view revenue in his career.
