Travis Kelce caught fans by surprise on Thursday night with a surprise announcement about a mystery guest on his New Heights podcast – with the episode set to be broadcast the day he marries Taylor Swift.

The world is watching Madison Square Garden with Swift and Kelce set to hold an intimate rehearsel dinner on Thursday night before hosting a party with around 1,000 guests at the venue in the heart of Manhattan on Friday night.

But the NFL star appears to have another surprise up his sleeve on the big day, via the popular podcast he hosts with older brother Jason.

The New Heights social media accounts announced on Thursday night: ‘We’ve got a very special guest making their New Heights debut… NEW EPISODE TOMORROW.’

Fans were stunned and speculation erupted immediately over who the guest could be.

‘Hmmmm this must be huge. Can’t wait,’ one fan wrote.

Another joked: ‘We will be kinda busy tomorrow but thanks for letting us know!’

Others speculated that it could be Swift’s brother Austin, her father Scott or even the singer Ed Sheeran, who is in New York ahead of the big day and good friends with Swift.

Eagle-eyed fans, however, noticed one clue in the preview image shared by New Heights.

Kelce appears to be wearing the same blue checkered shirt he was pictured in during his bachelor party.

It is not known exactly who every member of his celebration was, other than his brother also being there.
