X FACTOR 2011 winners Little Mix are joining JLS’ Sound City Summer Tour, we can exclusively reveal.

They will be joined by rising stars Cover Drive.

Jesy, Perrie, Leigh-Ann and Jade were the first girl band to reach the final of the hit ITV1 show and the first group winners.

They went straight to number one in the UK singles charts with their cover of Damien Rice’s Cannonball and X Factor judge Gary Barlow is writing songs for their forthcoming album.

Cover Drive have had two UK top ten singles, including the number one single Twilight earlier this year.

The four-piece band from Barbados’ third single Sparks, out this week, looks likely to do the same; clocking up more than a million views on YouTube.

“While we’ve known for a little while Little Mix might join JLS and Alexandra on this summer tour, to be able to finally confirm it is amazing,” says tour spokesman Dion Clements.

“With Cover Drive, this tour offers unbeatable value for music fans and places this tour firmly at the top of the must-do list for the summer holidays.”

The full line-up to date now stands at JLS with special guest Alexandra Burke, Little Mix, Cover Drive and A*M*E.

The Chantry Park, Ipswich, concert takes place on Sunday, August 26. Tickets are on sale via the Ipswich Regent box office in person, by calling 01473 433100, visiting www.ipswichregent.com, visiting www.nationalboxoffice.co.uk or calling 0871 224 1112/1113.
