Pharrell Williams and The 1975 have been added to the line-up for Radio 1's Big Weekend 2014.
They join Rita Ora and Paulo Nutini as the only acts announced to play the free festival so far.
This year's Big Weekend will take place at Glasgow Green over the weekend of May 23, 24 and 25.
The festival is heading to the Scottish city to coincide with this year's Commonwealth Games, which will be hosted by Glasgow later this year.
Jason Carter, Head of Live Music and Events, Popular Music added: "Radio 1's Big Weekend is the biggest event in the station's calendar and we are delighted that Glasgow will host the event for the very first time in 2014.
"It's shaping up to be a stunning artist line-up, and the City will no doubt be buzzing across the weekend."
