While performing at Madison Square Garden on Aug. 29, Harry Styles couldn't help himself from joking about his ex Taylor Swift's wedding.

The singer gave a cheeky shout-out to ex Taylor Swift’s wedding to Travis Kelce at MSG at the end of his concert Saturday night.

“We’re at Madison Square Garden, home of the world champion New York Knicks! And they also do weddings," the Grammy winner said during his Aug. 29 show.
