Australian boy band 5 Seconds of Summer has hit the top of the UK music charts with their single She Looks So Perfect.
The teenage four-piece, known as 5SOS, knocked Duke Dumont's I Got U off the number one slot.
She Looks So Perfect also reached No.1 in Australia this week, and makes 5SOS only the fourth Australian group to reach the UK No.1 and the first to do so since Madison Avenue's Don't Call Me Baby in 2000.
The quartet of Luke Hemmings, Mikey Clifford, Calum Hood and Ash Irwin all hail from Sydney and have an average age of 18.
They shot to fame after posting covers of Justin Bieber and Ed Sheeran songs on YouTube. They were invited to support One Direction on their Take Me Home world tour.
