Taylor Swift and Travis Kelce may have just announced their engagement, but the preparations are already underway to make their wedding day flawless.

An insider shared with the Daily Mail that the couple has already made several important decisions, including opting for a small and intimate guest list.

‘It will just be close friends and family,’ revealed the source, highlighting that the 14-time Grammy winner and her NFL star fiancé, both aged 35, ‘are actively planning and have many details already arranged.’

Without question, their wedding day will be a true family affair.

Swift’s parents, Andrea, 67, and Scott, 73, will be there alongside her younger brother, Austin, 33.

Kelce will be supported by his parents, Donna, 72, and Ed, 74, along with his brother Jason, 37, Jason’s wife Kylie, 33, and their four young daughters.

Beyond family, the couple’s closest friends are also expected to be part of the celebration.

Swift’s tight-knit group includes Selena Gomez, Ashley Avignone, Zoë Kravitz, and Abigail Anderson, alongside the Haim sisters, who are like family to her.

Brittany Mahomes, wife of Chiefs quarterback Patrick Mahomes, has become one of Swift’s newest confidantes.

On Kelce’s side, his childhood friend Kumar Ferguson and early hockey teammate Aric Jones are expected to be present, as well as former Kansas City Chiefs star Ross Travis, who has been one of Kelce’s closest friends since 2015.

Together, they represent the tight-knit community the couple have built around them and the very people they’d want cheering them on as they say ‘I do.’

There is speculation too that the wedding could be much sooner than fans ever expected.

Earlier this week, another source close to the lovebirds claimed Kelce orchestrated the proposal completely on his own and made sure it was old-fashioned in all the right ways.

‘Travis 100 percent planned this by himself,’ the insider told the Daily Mail. ‘He wanted it to be completely traditional — that he would choose the ring and ask for her to marry him.’

That approach apparently lined up perfectly with Swift’s own vision for the moment.

‘Based on what he’s told me, she would want the whole thing to be traditional, too. She wants him to take the lead,’ the source added.

Before getting down on bended knee, Kelce first asked Swift’s parents for permission. 

‘It was of extreme importance to do that, because he wanted it to mean something for everyone involved,’ our insider said. ‘This is a dream for him, and he knows that Taylor always wanted to get married.’

According to another source, Kelce’s mother Donna, 72, was equally thrilled. 

‘Donna is delighted, and says that everyone in her family adores Taylor and they love her family as well. This was a family affair. Both families love and respect the other, and both knew ahead of time what was up,’ that source said. 

Friends of the couple weren’t surprised by the happy news, in fact, many say they saw it coming a mile away. 

‘Travis literally always said she’s the girl he’s going to marry,’ our insider said. ‘[He has] been saying that for a long time, really since the beginning.’

So much so that pals jokingly began calling him ‘Mr. Taylor Swift’ — a nickname Kelce has happily embraced.

One friend now predicts: ‘It’s going to be the wedding of the century.’
