One of the biggest names in boxing, Floyd Mayweather Jr., spent his time before his big match against Canelo Alvarez hanging out with one of the biggest names in Hollywood ... Justin Bieber, who Instagrammed the encounter.

Before the big Mayweather/Canelo match at the MGM Grand Garden Arena in Las Vegas on Saturday (Sept. 14), Bieber flew on a private jet with Elon Musk to Vegas to support the undefeated boxer.

"Go to showtime.net to get the fight and support the champ @FloydMayweather. I'll be there too," Bieber wrote in the caption of an Instagram selfie.

Mayweather sure loves to spend time with celebrities before his matches. Before spending time with Bieber, he walked into the ring accompanied by Lil Wayne before his last match on May 4. This time, the guys let Biebs tag along too. And apparently it didn't hurt because Mayweather won the match. Watch the video:
