JUST IN:Taylor Swift and Travis Kelce partied at Paul McCartney’s house, Jimmy Kimmel reveals…more details

Jimmy Kimmel is telling all about what it’s like to attend the “Avengers: Endgame” of parties. The late-night host chatted on “The Howard Stern Show” about going to a star-studded bash with dozens of famous guests, including Taylor Swift, Travis Kelce, Mick Jagger, Bruce Springsteen and Steven Spielberg.

The party was held at Paul McCartney’s house, and Kimmel explained he ended up there after going to a dinner whose host was invited to the gathering. There were about 100 guests, people were dancing in the kitchen, and Swift was DJing — although that may make her role sound a bit more involved than it was, according to Kimmel.

“She just had her iPhone and tapped into the house system,” he said. “It wasn’t like she was hired to work there.” But Kimmel confirmed that Swift’s boyfriend joined her at the party, and the comedian’s wife, Molly McNearney, chimed in that Kelce is “very good looking.”

The party was so ridiculously packed with A-list talent that Kimmel said he gravitated towards the people he already knew so they could say to each other, “Can you believe that this is happening and that we’re here?” He did, though, have a “good chat” with Springsteen.
