Rumors that Taylor Swift and Travis Kelce are already engaged have continued to heat up after the singer brought her boyfriend on stage in London.

The pop star, 34, sent fans completely wild when her NFL star boyfriend, 34, joined her on stage for a skit during her third Wembley Eras tour show on Sunday night.

Decked out in a tuxedo and top hat, the Kansas City Chiefs player carried Taylor across the stage during her I Can Do It With a Broken Heart outfit change.

Taylor also went Instagram official with Travis on Friday after almost a year of dating as she shared a snap of them smiling with Prince William and his children George, 10, and Charlotte, nine.

The rare public declarations of their love have left fans convinced that the couple have already secretly got engaged, or are on the verge of the big question.

Outspoken podcast hosts Amy, Sophie & Kate Taeuber speculated things are getting serious between the pair as they pointed out Taylor never usually brings her partners’ out on stage.

‘This is soulmate sort of s**t,’ the journalists speculated. ‘You don’t bring up some guy you’re casually dating and put him on stage for the rest of the world to see.

‘I think an engagement is happening, maybe it will happen on their one-year anniversary.’

‘I don’t think Travis is ever going to propose in public or on stage, it would be a private affair,’ they added, potentially hinting at a secret engagement.

They commented on Taylor going Instagram official with Travis, almost a year after they were first linked in August 2023, in a sign that they are taking the next step.

‘Everyone knows they’re official and they’re together, but this is the first time she’s posted about him, and also the first time she’s posted about a boyfriend in quite some time,’ they added.

Taylor has previously kept her high-profile romances with her exes including Joe Alwyn and Tom Hiddleston relatively under wraps, not posting them to social media.

Taylor’s eager band of ‘Swifties’ have been adding to the engagement rumours, taking to X – formerly known as Twitter – after Travis’ on-stage appearance to speculate.

Some fans remarked that Travis carrying Taylor across the stage felt ‘symbolic’ of a groom carrying a bride over a threshold as their theories went wild.

One wrote: ‘I’m sorry but no one can convince me otherwise: THEY ARE ENGAGED! and that’s why no one’s ever had her, not like him. I am really happy that Tay found her person and @taylorswift13 pls let us come to the wedding.’

A second person tweeted: ‘I think #TaylorSwift and #TravisKelce are ALREADY engaged!!!!!!,’ while a third shared: ‘They are already secretly engaged, if not more.’

‘I don’t give a f**k Taylor Swift and Travis Kelce are engaged,’ another added.

One fan also pointed out that Gigi Hadid gifting her bestie Taylor a ring in recent days could also hint at a recent engagement between the singer and Travis.

Supermodel Gigi, 29, bought Taylor an adorable custom-made and personalised ring featuring special details dedicated to Travis, further fueling fans’ suspicions.

The gold ring features a picture of Taylor’s famous cat Benjamin Button, as well as Travis’ Jersey number ’87’ inside a flaming love heart on one side of the band.

The piece of jewellery also includes her favourite number 13 as well as an engraving of the initials of her new album, The Tortured Poets Department.

‘This ring is designed to keep her favorite things close,’ the ring’s creators Cece Jewellery shared in an Instagram post.

One fan claimed of the ring: ‘If this doesn’t say they’re probably already engaged! What friend gets you jewelry with just a boyfriend’s number because if they break up she won’t wear it again. But if they’re getting married….’

Taylor and Travis have been romantically linked since 2023, but have generally kept their romance low-profile, only going more public with their union in recent weeks.

Travis has been every inch the supportive boyfriend during Taylor’s Eras tour, jetting around the world to watch her perform as he has been spotted in the stands.

But the couple took things one step further in London over the weekend as Travis joined Taylor on stage during her outfit change for an amusing skit and dance routine.

During his brief appearance, the tight end grinned as he carried his girlfriend across the stage and gently placing her on a red couch before she changed outfits.

The appearance sent Taylor’s fans wild as they were left in awe at Travis’ professional performance, which even saw him show off some of his signature dance moves.

Their first on-stage performance together came just days after Taylor finally went Instagram official with Travis after almost one year of dating.

Amid her sold-out Wembley shows, the pop icon posted an epic selfie with Travis, Prince William, Prince George and Princess Charlotte taken backstage.

‘Happy Bday M8! London shows are off to a splendid start @princeandprincessofwales,’ the Cardigan singer captioned the incredible snap, referring to the future King of England’s 42nd birthday.

Taylor continued the rare public display of love for her boyfriend just days later as she admitted she was left ‘swooning’ by him making his Eras tour debut with her.

She shared snaps of herself and Travis on stage together as she gushed over his appearance with her on stage.

‘Wembley Stadium round one was so surreal. Looking out into crowds of 90,000 fans each night and hearing that VOLUME… Those were some of the loudest crowds I’ve ever heard,’ she penned.

‘And I’m still cracking up/swooning over @killatrav’s [Travis’] Eras Tour debut. Never going to forget these shows.’

Taylor has wrapped up her three June Wembley shows but is set to return to the iconic London venue once again for five more shows in August.
