Swifties have been all over the Travis Kelce X Taylor Swift hype recently.
Things really kicked up a notch when the 34-year-old 'Cruel Summer' singer brought the NFL star, 34, out on stage with her during Sunday's (23 June) Eras Tour show at London's Wembley Stadium.
And the buzz around the power couple is only growing especially after Travis spilled all about another memorable celebrity crossover on his podcast yesterday (26 June).
So, in case you're not caught up, Taylor surprised her fans by sharing a selfie with future king Prince William and two of the Royal children, after the family attended the concert.

On Friday night (21 June), the Prince of Wales - along with two eldest children Prince George and Princess Charlotte - was spotted dancing to the pop icon's 2014 hit 'Shake it Off'.
It wasn't just the Royal additions to singer Taylor's recent upload, however, that sent fans into a frenzy - it was the fact that Travis also joined in for the iconic photo.
It later became apparent that he and his fellow American football player brother, Jason, had joined the soirée with the Royal youngsters.
And now, in the latest episode of their New Heights podcast, Travis revealed why he 'broke royal protocol' when meeting Prince William at the show.

He explained: "We met royalty, guys. There was royalty at the show. I got there early and got to meet Prince William. How bout that? Your Royal Highness.
"Dude, he was the coolest motherf**ker. He was so cool."
Jason then chimed in: "He was awesome. He was a good dude."
Travis continued, this time addressing British etiquette: "He was there with little George and Charlotte, and they were an absolute delight to meet.

"I wasn't sure if I was supposed to bow to them - courtesy [or] just be an American idiot and shake their hand. We wanted to be polite, especially on this side of the pond."
Jason, who is the former Philadelphia Eagles centre, then explained how they 'broke royal protocol' as they didn't have to bow to the Prince in this instance.
"We did get a warning because, honestly, we don't know the actual [etiquette]," he said.

"Because we weren't at an elegant, official royal event, we didn't have to bow. If it would've been an official meeting-of-royalty event, then it would have been that."
Jason concluded: "They were wonderful people, and that's what it's about. They're part of a monarchy... [it's] hard to be a down-to-earth human being - I would assume. But [they] came off that way completely."
