Harry Styles Calls Out Old Friend for Stealing Girlfriend

He did it in the middle of a concert in the middle of thousands of fans.

"I was about 14 years old," he said to the crowd. "And Jack ... stole my girlfriend."

The crowd was not happy.

Jack was all smiles, but Styles said "feel free, little kicks, little digs on the way out" to him.

A bandmate is heard saying, "That's no way to treat your friends."
