The stars flocked to Las Vegas to witness the “fight of the century” as Floyd Mayweather Jr. took on Manny Pacquaio for the welterweight title on Saturday. While the prized fighters faced off inside the MGM Grand Garden Arena, everyone from Denzel Washington to Paris Hilton was ringside for the main event.

Hip-hop’s royal couple was dressed to the nines; Jay Z donned a tuxedo and Beyoncé was a knockout in a red-caped jumpsuit. They snapped pics with the newly-engaged Nicki Minaj and Meek Mill, who came out to support the Money Team.

Justin Bieber cleaned up nicely in a suit as he escorted his undefeated pal Mayweather into the ring, while Pacquaio was flanked by a Bieber-impersonating Jimmy Kimmel.

There were plenty of other couple sightings. Diddy brought Cassie as his date, Bow Wow stepped out with his fiancée Erica Mena, and Lil Wayne couldn’t keep his hands off girlfriend Christina Milian.

Meanwhile, Weezy’s embattled Cash Money boss Birdman bet big on Mayweather and walked away with a huge payday.

Before Mayweather defeated Pacquaio by unanimous decision, Jamie Foxx stepped into the ring to perform a soulful rendition of the national anthem.
