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.
