Justin Bieber will carry Floyd Mayweather's championship belts into the ring before his fight against Manny Pacquiao on Saturday, May 2.
The undefeated boxing champion has reportedly asked the "Boyfriend" hitmaker to lead his entourage into the ring ahead of his $230 million showdown at the MGM Grand in Las Vegas this weekend.
Mayweather, 38, first became friends with the 21-year-old star because his 14-year-old daughter Iyanna is a huge fan of the heartthrob.
A source told The Sun newspaper: "As long as his daughter wants Justin there he'll be his main man. They get on really well."
Justin has been at Mayweather's side for a number of fights and public appearances and even made a surprise appearance at Iyanna's birthday party last year.
The singer is also reported to have invited his ex-girlfriend Selena Gomez, who recently split from the DJ Zedd, to accompany him to the fight.
However, he's since said to have asked his pals Kendall Jenner and Hailey Baldwin to come along too.
A source told HollywoodLife.com: "Selena would have gone with Justin, but not with him, Kendall and Hailey. There's no way on earth that would happen."
Meanwhile, Jamie Foxx—who recently rubbished claims he's been dating the actress Katie Holmes—is set to sing the US national anthem before Mayweather's highly-anticipated fight against the Filipino world champion.
