Why Travis Kelce isn’t traveling to NYC to be with Taylor Swift on her birthday

A source confirms to Page Six that the Kansas City Chiefs player will remain in Kansas City, Mo., on Wednesday for mandatory practice.

The “Bad Blood” singer traveled to the Big Apple Tuesday to kick off her birthday celebration at club Zero Bond with BFF Selena Gomez, actor Miles Teller and his wife, Keleigh Sperry.

The trio was photographed leaving the private membership club that night after Swift skipped the ceremony for Time Magazine’s Person of the Year gala earlier that evening.

Although Kelce won’t be able to make it to NYC for his girlfriend’s big day, he was able to celebrate with her a few days early.

The tight end, also 34, and the Grammy winner — who went public with their romance in September — packed on the PDA at a post-game holiday party in Kansas City following the Chiefs’ home loss to the Buffalo Bills Sunday night.

The power couple got close as they smiled for the camera with friends. At one point, Swift and Kelce shared a steamy kiss while enjoying the festivities.

The “Cruel Summer” songstress wore a black leather mini skirt, a low-cut, sequin-lined bodysuit, sheer tights and knee-high boots, while her beau sported a plaid jacket, khaki pants, white sneakers and a beanie.

Before the outing, Swift cheered on Kelce and his teammates from a VIP suite inside Arrowhead Stadium.

The pop star wore a vintage Chiefs sweatshirt, which was gifted to her from Westside Storey, at the game.

The two-time Super Bowl champion was seen looking downcast as he exited the stadium hand-in-hand with Swift after he and his team lost to the Bills by three points.
