5 Seconds of Summer have hit No.1 on the UK iTunes chart.

The Australian group released their 'She Looks So Perfect' EP in the country on Sunday (March 23) and it is enjoying huge success via digital sales.

At the time of writing, the tune is currently sitting at No.1 on the UK singles chart on iTunes.

Current UK No.1 Duke Dumont is No.2 with his track 'I Got U' whilst Route 94's 'My Love' is No.3.

5 Seconds of Summer meanwhile have yet to release their first album.

The band, however, have supported the likes of One Direction and they look set for big things.
