One Direction think The Wanted are two-faced.

The 'Live While We're Young' hitmakers refuse to slam their boy band rivals, but are disappointed that The Wanted hunks feel the need to criticize them behind their backs.

Liam Payne - who has been linked to Leona Lewis since splitting from long-term girlfriend Danielle Peazer - told Fabulous magazine: ''The only thing that's bad for me about them is actually they were really nice to our faces, but when it came to talking to the media they were really trashy about us.

''We'd never done anything wrong, we were just running around doing our thing. We'd never purposely talk trash about anyone and we still haven't said anything about them now.''

The five-piece - also comprising Zayn Malik, Harry Styles, Niall Horan and Louis Tomlinson - denied the bands are in competition with each other for chart domination, yet hinted that their own mass appeal outshines The Wanted's success.

Liam, 19, continued: ''I don't think there's any real competition about us. They sing dance music.

''They're real lads' lads whereas we're just mischievous, which I think is different. For me, you just look at twitter followers, which I think is a big player.''

Meanwhile, The Wanted recently joked that they couldn't compete with the popularity of their cheeky younger rivals, when Jay McGuiness quipped: ''It is depressing. But we are hairier and more decrepit. We are the ropier version.''
