Prince William urged One Direction to get in on a picture of his wife Duchess Catherine, 'photo bombing' the royal.
Hitting it off with the group during their time at this year's Royal Variety Performance in London, the Prince attempted to get the guys to steal the spotlight from his spouse whilst she was getting her picture taken.
Liam Payne told The Sun newspaper: "Kate was doing a shot with Michael McIntyre but the camera was looking right at us.
"So Wills said, 'I'm sure we can get a couple of photo bombs in here, lads. Let's go for it'."
Niall Horan added: "We were pulling silly faces in the background."
Despite getting on well with the royal couple, the band admit that before the meeting they were nervous, especially Liam.
"When we first met them at the start it was so, so scary. My palms were sweating.
"When I was talking to Kate I had to wipe them on the back of my trousers -- but it looked like I was rubbing my a**!"
William also took the time to discuss football with the group and offered to help smooth tensions between Louis Tomlinson and Aston Villa striker Gabriel Agbonlahor after a nasty tackle from the sportsman forced the singer out of a charity game in September.
Niall went on to explain: "We were talking with William about football because he is a Villa fan.
"I told him Louis had had a bit of an altercation with Agbonlahor.
"Then William said, 'Oh, I wasn't going to bring it up but I'll have to have a chat with him'."
Louis said: "Yeah, that a***hole Agbonlahor -- I got nobbled by him. He said he was going to throw him out actually...
"It was unbelievable. He asked me, 'How's Doncaster doing?'
"At first I didn't realise what he was talking about then I realised he meant Donny Rovers.
"I said, 'Not so great, unfortunately'. But it was amazing that he knew it was my team."
