Travis Kelce screamed Beastie Boys lyrics into CBS’ microphone in a rowdy postgame speech following the Chiefs’ AFC Championship victory in Baltimore on Sunday.

Kelce had 11 catches for 116 yards and a touchdown as the Chiefs booked a trip to the Super Bowl for a second straight year.

‘The Chiefs are still the Chiefs, and believe it,’ he said on CBS after the game, before invoking the Beastie Boys. ‘You gotta fight, for your right, to party!’

‘Believe it, baby, we going to Las Vegas, Nevada to go get us another one!’

Quarterback Patrick Mahomes added to CBS, ‘We’ve been underdogs for the last few games, but we never feel like underdogs. We got a lot of guys on this team that know how to win, and when playoffs came around I knew we were gonna make it happen.’

Travis Kelce and Taylor Swift shared a kiss on the field following the Chiefs’ win

Kelce could be seen embracing his brother (and Eagles star) Jason and girlfriend Taylor Swift on the field after the game.

Travis and Taylor hugged and kissed at M&T Bank Stadium, with the pop megastar looking almost tearful as the couple had a moment to celebrate.

It is now assumed that Swift will dash from Tokyo to Las Vegas to watch her boyfriend battle for football’s ultimate prize on February 11.

Swift plays four nights of her blockbuster Eras Tour in Japan’s capital from February 7-10 before now having to race back to Allegiant Stadium in Las Vegas.

It was also a significant night for Kelce individually, as he broke Jerry Rice’s record for most postseason receptions in NFL history in the first half.

The 34-year-old went into Sunday’s game with 145 receptions, 1,694 receiving yards and 18 touchdowns in his playoff career, trailing the Hall of Famer Rice in each category.

But with seven early catches, Kelce brought his tally up to 152, surpassing Rice’s 151 before halftime.
