Travis Kelce’s Taylor Swift photo dump was more than just his way of making their romance Instagram-official — according to a source, it was also proof that he’s “serious” about the “Love Story” songstress.

“It was intentional,” an insider told People on Friday. “They’ve been private in their own way, but this was his way of showing how serious things have become.”

The source added that the couple is “in a really solid place and more in sync than ever.”

Reps for Swift and Kelce did not immediately respond to Page Six’s requests for comment.

The Kansas City Chiefs tight end and “Blank Space” singer, both 35, began dating in September of 2023 — however, it took until Thursday for the athlete to share relationship highlights to his personal account, captioning the carousel, “Had some adventures this offseason, kept it 💯.”

The intimate look into their romance included pics of Kelce and Swift rocking matching caps, enjoying drinks with friends and snuggling up during a snowy outing.

In a sweet photo of the pair in a restaurant, eagle-eyed fans noticed that Kelce’s iPhone lock screen featured a photo with Swift.

Still more tantalizing, a zoomed-in look at the pic revealed the “Cruel Summer” singer rocking rings. However, according to a source for TMZ, they were the athlete’s trio of Super Bowl rings — not an engagement token.

Kelce’s comments thread featured some high-profile support. “things we love to see: travis happy 🥹❤️,” wrote the official Kansas City Chiefs account, while pal Patrick Mahomes remarked, “❤️💪🏽”

“The whole world happy for y’all,,, may God continue to bless you and your families with happiness and pure joy 🙏🏾,” gushed rapper Flavor Flav.

“i’m printing so many of these for my wall,” wrote MTV’s official account, while purveyor of sweet baking products, Betty Crocker, wrote, “This might break the internet.”

The NFL star’s big social media moment landed amid a pivotal summer for the famous couple, as Swift wrapped up her Eras Tour in December and Kelce finished his season with a Super Bowl loss in February. “It’s been a turning point for their relationship in a lot of ways,” an insider told People earlier this month.

“They’re incredibly happy and in sync. There’s a calmness and ease to their relationship right now that’s been really grounding for Taylor and Travis.”

They continued, adding that the couple is “soaking up every minute of this slower season together.”

“They’ve been splitting their time between New York, Nashville, and a few quiet getaways, just enjoying each other’s company without all the usual chaos,” the insider said. “This kind of downtime is rare for both of them, and it’s really allowed their bond to deepen.”
