“Where is Taylor Swift?” Fans are asking, As Travis Kelce attends Justin Timberlake’s concert without his partner…

Travis Kelce showed his support for longtime friend Justin Timberlake at his concert Wednesday night.

An Instagram Story posted by music producer Khris Riddick-Tynes revealed the Kansas City Chiefs tight end in the background bopping his head to the “Mirrors” crooner’s hits; however, Taylor Swift was nowhere to be seen.

Although the “Cruel Summer” singer missed out on the star-studded event, Kelce and fans were treated to a surprise *NSYNC reunion. The boy band hopped on stage to perform their massive hits “Bye Bye Bye” and “Girlfriend.”

A rep for Swift didn’t immediately return Page Six’s request for comment.

Although Kelce, 34, and Swift, 34, rushed back from Singapore to attend Madonna’s ultra-exclusive Oscars bash, the couple hasn’t been seen together since.

The NFL player stepped out for lunch at Cecconi’s with a group of friends on Monday sans the pop star.

Kelce looked handsome in a cozy, cream-colored sweater, white shirt, Hermès belt, olive green slacks and dark sunglasses — perhaps an attempt to cover up the exhaustion from his outing the night before.

Although the “Blank Space” singer hasn’t been photographed since leaving Asia, she’s likely leaning into her two-month hiatus from the Eras Tour to get some much-needed rest after she began to appear fatigued.

She pushed through and Kelce managed to catch two of her concerts where fans captured him dancing to “Bad Blood” and other tunes.

Yeah outside of that, got to eat some lovely Singapore food and just catch the views. Everything over there just seems so nice.”

It won’t be all rest, however, as Swift is set to release her new album, “The Tortured Poets Department,” next month.

“What an unforgettable way to end this leg of the tour!!” Swift captioned a series of photos from her Singapore performances.

“See you in May when we get back to the Eras Tour!! In the meantime I’ve got an album to release…”
