Have we seen the last of Floyd Mayweather in the boxing ring? Despite what he says, probably not – though he sure seems to be enjoying retirement.

While you were stressing over Hurricane Joaquin, Mayweather spent the weekend chilling in Bora Bora with his BFF (who also thinks you're stupid), Justin Bieber. According to Mayweather's Instagram, the two stayed in the St. Regis' Royal Overwater Villa – a 2,852 square foot room with private terraces and a lagoon-side infinity pool – where they did all the things best bros do on a getaway weekend, like take in the idyllic scenery with a cup of tea or swim in subterranean passageways while a professional videographer captures the action for posterity.

And if all that wasn't enough, Mayweather and Bieber also made like a pair of proper tourists, hitting up karaoke night at the hotel. We're told this is footage of Biebs performing his song "What Do You Mean?" and then the Beatles' "Let It Be" on piano – apparently barefoot, because he was on vacay.

And since it was a day that ended in "-y," Mayweather also took the opportunity to flaunt his wealth on social media by showing off some rolls of cash, which Bieber dutifully counted for him. Incredibly rich best buds for life!

Recently, rumors have begun swirling that Mayweather may get in the ring one more time to take on a healthy Manny Pacquiao in a rematch of their totally sucky "Fight of the Century," but if this is what retirement is like for the wealthiest athlete in the world, maybe we really have seen the last of Mayweather. Would you blame him? Didn't think so.
