Harry Styles urged fans to "kick" an old schoolfriend who "stole" his girlfriend.
The 'Steal My Girl' hitmaker's childhood pal Jack Robinson was in the audience during One Direction's 'On The Road Again' show in Oslo, Norway, at the weekend, and the 21-year-old singer couldn't resist drawing attention to his old friend.
He said: "I have a friend from school in the audience tonight called Jack Robinson, he's over there.
"I'm going to tell you a quick little story before we do the next song.
"I was about 14 years old and Jack Robinson stole my girlfriend.
"If he's still there at the end of the show, feel free, little kicks, little digs on the way out. I love you, sir!"
And Harry's bandmate Liam Payne also reprimanded Jack after hearing the story.
Liam said: "Jesus Christ Jack that's no way to treat your friends."
Jack took the dig in good spirits and was seen on the big screens in the venue smiling and laughing.
Meanwhile, during the show, prankster Louis Tomlinson soaked Liam's girlfriend Sophia Smith after he spotted her leaving early.
As she walked past the front of the stage with a member of security staff, the singer threw the contents of his water bottle at her, but she shrugged off the incident and laughed.
