One Direction star Liam Payne has described his bandmate Harry Styles as "the biggest celeb flirt in the world".

Talking to The Mirror, Liam revealed that Harry's phone is filled with famous names - but he's not too keen on sharing them.

"Harry has loads of secret celebrity phone numbers and we find out about them later," Liam explained.

"We'll see something in the papers and be like: 'What's going on here?' and he'll be like: 'Oh, it's Gary from Take That or whoever, don't worry about it'."

Of course, Harry's [uuid=b3625b35-7eb3-475d-a09f-ad82945cb74f]popularity with the ladies[/uuid], celebrity or otherwise, is no secret.

Asked about the curly-haired heartthrob's reputation, Liam said: "He's a cheeky little lad, isn't he? Well, he's not really that little, but you know what I mean.'

In other 1D news, the boys have reportedly broken another record with their first ever DVD.

Up All Night: The Live Tour has made chart history by outselling the number one album on America's Billboard 200 - the first time a DVD has ever outsold an album in US chart history.

In fact the DVD, which features footage from the lads' live tour, has topped the charts in no less than 25 charts across the world since its release.
