Taylor Swift is currently on a break from the Eras Tour and has been spending lots of time with Travis Kelce in his home base of Kansas City, as well as frequent trips to hang with friends in New York City. Some pretty cute pics of the couple together have been circulating around the internet, including another new shot of Swift kissing Kelce on the cheek, so it seems like things are going quite well for the couple.

But back to the birthday! The clock is ticking, and a source told Us Weekly that Kelce “wants to throw the best party possible” for his superstar girlfriend. The source said that the party will be in NYC and that Swift’s celebrity besties will all be invited — likely Selena Gomez, Emma Stone, Jack Antonoff, Blake Lively, the whole gang. “Money is not an object,” they shared.

Another source told Life & Style that Kelce is planning an “intimate” dinner for himself and Swift, followed by the gathering of friends. “He’s arranged a very intimate, romantic dinner just for the two of them, and is also trying to pull off a semi-surprise party with the help of some of her closest friends,” the source said, adding that friends are hoping Kelce proposes that night. (We probably don’t have to remind you, but this is an unnamed source, so take that anecdote with a giant grain of salt.)

Of course, Swift is a self-proclaimed “Mastermind,” so if Kelce does manage to pull off a genuine surprise party, that’s no small feat. We’ll be on our vigilante sh*t keeping our eyes peeled for any hints at the December 13 celebrations.
