AceShowbiz - Harry Styles ended the European leg of his world tour on Monday night, April 16 by playing a prank on support act Mabel. The singer was in the middle of her set in Dublin, Ireland when the One Direction star crept up behind her and pushed a cream pie in her face.

The stunned newcomer giggled and hugged Harry as fans applauded, and then completed her set as the headliner exited the stage.

She later posted video of the practical joke that left her covered in cream on Twitter, captioning it, "When @Harry_Styles pranks you on stage and throws a cream pie in your face whilst you're singing. At least it was vegan."

When Harry Styles pranks you on stage and throws a cream pie in your face whilst you’re singing. At least it was vegan 🙄 Big love to you @harrystyles and the whole crew and band for making this tour so special. I’m gonna miss you all 💔
