Like with much of the Swift-Kelce wedding, the details on who might attend are completely unclear, too. But it hasn’t stopped the internet from speculating.

Friends and family have largely evaded questions – among them Kelce’s sister-in-law.

NFL San Francisco 49ers player George Kittle, singer Benson Boone and English actress Suki Waterhouse have been some of the few so far to confirm they’ll be going, but haven’t provided any details.

But a barrage of celebrities from all over the globe have recently been spotted in the Big Apple just ahead of the celebrations, adding to the speculation.

Mother of the supposed groom Donna Kelce was seen arriving in New York City on Thursday, hours before the supposed rehearsal dinner at Madison Square Garden.

Singer Ed Sheeran, Fleabag actress Phoebe Waller-Bridge, singer Camila Cabello and actress Anya Taylor-Joy, all of whom have been known to socialize with the star, were also spotted in the area.

Among the stars in the Big Apple is BBC TV presenter Graham Norton, who Swift invited to the ceremony on his BBC chat show last year.

BBC Radio 1 host Greg James, who Swift personally invited while promoting her latest album, could be there, though he has not offered any details.

Longtime friend Selena Gomez and frequent collaborator Jack Antonoff are expected to be guests. As is childhood friend Abigail Anderson Berard, who has been in multiple Swift music videos.

Some fans are curious to see whether her one-time bestie actress Blake Lively, who drew Swift into a bitter legal battle with Lively’s It Ends With Us co-star Justin Baldoni, will be invited. And former pal, model Karlie Kloss, is among those who have reportedly received an invite.

Other speculation has revolved around potential performers, including Stevie Nicks and Tim McGraw – music legends who have inspired the superstar throughout her career. The speculation could be connected to Swift wearing a T-shirt that read “Stevie Knicks” when she was at MSG earlier this month for a Knicks basketball game.
