Jake Paul Looks Good at Party After Anthony Joshua Breaks His Jaw

Jake Paul's jaw may have taken a beating Friday night, but you couldn't tell from looking at him Saturday ... because he seemed ready to let loose at a big after-party!

The influencer-turned-boxer attended a party thrown by Celebrity Sports Entertainment at a private mansion in Miami ... and, he looked like his usual self while walking into the affair -- shaking hands with guests and strolling through like nothing happened, though he did keep the chatter to a minimum.

JP posed for pics ... putting up his fists like he's ready for another fight despite Anthony Joshua knocking him out.

Jake's brother, Logan Paul, was at the invite-only, One Water-powered event ... showing off his chiseled abs in an open denim button-down and filming an episode of his popular "Impaulsive" podcast during the party.

Renowned celebrity illustrator and painter Robert Prior made live art ... sketching a portrait of Jake ready to throw down in the ring ... while Jake's mom, Pam Stepnick, signed copies of her book, "F*** the Pauls: Written by Their Mother." The party didn't skimp on music either, with tunes played throughout the evening by Netflix and the Paul brothers’ DJ, E-V and Vic Latino. The shindig was all packed with sponsors, including Dog Haus Dogs, Casa Noosh with premium caviar service and 1-800-Liquors, all alongside alongside Betr Sportsbook and Jake's body-care line, GetW.

While Jake didn't necessarily look worse for wear, he was probably still feeling some sting in his face after Joshua knocked him down twice in the fifth round of Friday's fight before putting him on the canvas for good in the sixth.

Paul wasn't too bummed after the fight, saying ... "I'm feeling good. That was fun. I love this sport" -- all while dealing with the aforementioned broken jaw. Despite breaking his jaw in two places, Jake posted that he's ready to fight again ... challenging Canelo Alvarez to a brawl.
