Taylor Swift celebrated with Travis Kelce Sunday night at his steakhouse, 1587 Prime … and we’re guessing he destroyed his filet just like the Chiefs annihilated the Raiders.

Travis and Taylor were filmed by a fan making their way through the K.C. joint that TK co-owns with Patrick Mahomes.

Prior to date night … Taylor managed to avoid TV cams at Arrowhead. She was, however, filmed by a fan in her suite.

ICYMI .. The Chiefs beat the Raiders 31-zip.

Taylor has attended several games for Travis this season — including one where she snuck in behind a protective screen — though she didn’t make an official debut until last week when she was finally eyeballed.

As for dropping by Prime … TS had been there before, of course — even being a part of the restaurant’s soft opening last month.

Travis and Taylor have signature cocktails on the menu — his “Big Yeti” packs Gentleman’s Cut Bourbon, Bulleit Rye, nocino, demerara and bitters, while her “Alchemy” mixes vodka, dry curaçao, aronia berry, cranberry, strawberry, lime and oolong.
