Saquon Barkley was partyin' like he was back at Penn State Sunday night ... the Eagles star was shotgunnin' beers after securing his first Super Bowl win with Philly!
And, it was his 28th birthday!!!
The celebration was on after the Eagles whooped the 2x defending champ Kansas City Chiefs, 40-22, in Super Bowl LIX in New Orleans.
It's the second championship for the franchise and a first for many Eagles players, including Barkley, who signed with the team this offseason.
