Travis Kelce posted pictures of him and Taylor Swift to show 'how serious things have become'

Travis Kelce decided to post pictures of him and Taylor Swift on Instagram because he wanted to show “how serious things have become”.

Earlier this week, the Kansas City Chiefs tight end shared a carousel of photos from his off-season to the social media platform and for the first time ever, he included pictures of his superstar singer girlfriend Taylor.

A source told PEOPLE: “It wasn't random. It was intentional. They’ve been private in their own way, but this was his way of showing how serious things have become."

"They’re in a really solid place and more in sync than ever.”

Travis shared 13 images of himself posing with loved ones and seven of those pictures included Taylor.

He captioned the set: “Had some adventures this offseason, kept it 100.”

Flavor Flav commented: “The whole world happy for y’all,,, may God continue to bless you and your families with happiness and pure joy,” while Erin Andrews wrote: “FAVS”.

And, a comment from the official Kansas City Chiefs account said: “things we love to see: travis happy.”
