Having a ball!

Taylor Swift was photographed all over her rumored new “Lover” — Kansas City Chiefs tight end Travis Kelce — on Sunday at a post-game party.

In pictures first published by TMZ, the “Anti-Hero” songstress wraps her arm around the two-time Super Bowl champ’s neck as they mingle with his friends at a private event at Prime Social in Kansas City.

Kelce and Swift, both 33, were spotted jumping in a getaway car Sunday after the Chiefs beat the Chicago Bears 41-10.

Kelce raved about his day with Swift on Wednesday’s episode of his “New Heights” podcast, which he hosts with his older brother, Philadelphia Eagles center Jason Kelce, 35.

“She looked amazing,” Travis told his brother and professional rival, reminiscing on Swift attending the Chiefs game wearing his team’s colors and her signature red lip.

“Everybody was talking about her in great light and, on top of that, the day went perfect for Chiefs fans, of course.”

Also amazing is Travis’ jersey sales skyrocketing 400% after Swifties watched the Eras Tour mastermind scream “Let’s f–king go” when Kelce scored a touchdown.

Swift will be welcomed to New York — technically East Rutherford, NJ — on Sunday, as several reports claim she will cheer on Kelce as the Chiefs battle the Jets at MetLife Stadium.

Meanwhile, the “Bejeweled” singer is reportedly letting “Game of Thrones” star Sophie Turner, 27, and her two young daughters temporarily stay in an investment property she owns in Tribeca while the actress figures out custody with estranged husband Joe Jonas, 34.
