The cheeky singer happily obliged and filmed a 16-second clip for superfan Tash Gershfield - in which he asked her to leave her hubby and run off with him.
In the clip posted on Instagram Harry stares straight into the camera and tries not to giggle as he says, “Tash, you don’t have to go through with this”, before telling her he’ll be waiting at Borehamwood for a few hours if she wants to meet him so they can be together.
Joker Harry also showed his funny side at a recent charity football match, where he pranked Piers Morgan by running over and pulling his shorts down.
He also enjoyed a series of dates with Kendall Jenner in late 2013.
One Direction are currently performing concerts around the world as part of their ‘Where We Are’ tour, however, it hasn’t all been smooth-sailing for the band.
While the band were staying in Brazil, a video appearing to show Harry and Niall Horan dancing in their underpants in a hotel corridor emerged, and just weeks ago a clip of Zayn Malik appearing to smoke a ‘joint’ was leaked online.
The clip, filmed and narrated by Louis Tomlinson, sees Zayn smoking as Louis says: “So here we are, leaving Peru. Joint lit. Happy days!”
