JLS have advised One Direction to ignore the cameras while filming their upcoming 3D concert film.

The chart-topping boy band - comprising Harry Styles, Zayn Malik, Louis Tomlinson, Niall Horan and Liam Payne - announced earlier this month that they will be releasing their first documentary-style movie in August next year.

JLS: Eyes Wide Open 3D premiered last year, and band member Oritsé Williams has offered some words of wisdom to the five-piece.

He explained to Digital Spy: "I think all they've got to do is be themselves. Forget that the cameras are there - just be themselves, do what they do, have fun, enjoy it. And make sure they give their fans the biggest entertainment that they've come here to see.

He added: "With those kinds of things you can't focus too much on the cameras, or it takes over you, and you start being something that you're not. And then people are like, 'Oh, I didn't know he was like that'. But you're not really like that! Just be themselves."

The two former X Factor acts are famously close, and JLS star Marvin Humes say they regularly stay in touch.

He revealed: "Yeah, if we're not playing golf together or going to nights out, when we get the chance to - it's usually on BBM. I speak to Niall a lot. He's always messaging me about bits and pieces."
