Duo Nico and Vinz have become the first Norwegian act in almost three decades to top the UK singles chart.
A-ha was the last Norwegian act to hit number one in Britain in 1986 with their single The Sun Always Shines On TV.
Nico and Vinz's single Am I Wrong leapt 51 places to top the Official Singles Chart tonight.
"Growing up in Oslo, we always dreamed of being at the top of the UK chart, so for this now to be true is completely surreal. We are extremely grateful to you for making that happen," they said.
The track is at number 4 on the Billboard Hot 100 and has spent 16 weeks on the US chart.
