The back-to-back champs hit up Zouk nightclub at Resorts World with the Lombardi Trophy in tow to kick off the wild night of drunken debauchery ... and judging by the videos of the festivities, the vibes were at an all-time high.
Taylor Swift had to have been happy with the setlist ... as "Swag Surfin'" by Fast Life Yungstaz made the cut. Travis' older bro, Jason, also had a helluva time, rocking a luchador mask as he downed a drink.
The victors were already raging by the time they showed up to the venue ... as they started popping bottles right in the locker room after the 25-22 overtime thriller over the San Francisco 49ers.
But, the good times didn't stop after Zouk -- we're told the whole crew kept things going at XS nightclub afterward ... with Taylor staying there 'til 5:15 AM.
