Pixie Lott and Katy B are to perform at MTV Presents Titanic Sounds in Belfast.
The British songstresses join Olly Murs, Rizzle Kicks and Sean Paul to perform at the free gig to celebrate the new Titanic attraction in the Northern Irish city on April 13.
"I'm really excited to be going back to Belfast. You guys know how to have a good time! Woohoo!" said Pixie.
The festival-style pop event - which forms part of the city's Titanic Festival to mark the centenary of the historic ship's launch - will be filmed by MTV for broadcast on its channels from May 5.
Former X Factor finalist Olly is said to be playing with a full nine-piece band, and could be teaming up with Rizzle Kicks on their Top 10 hit Heart Skips A Beat.
Tickets are available from www.ticketmaster.ie, with a £5 administration fee.
