CHART-TOPPER Robyn has been added to the bill of stars appearing at this year's O2 Wireless Festival in Hyde Park between July 3-7.

The much-anticipated ann-ual festival, back for a fourth year, features the biggest names in rock, dance and pop as well as up-and-coming acts.

Swedish superstar Robyn had a number one hit last year with the single With Every Heartbeat and she will perform on the Live Nation stage on Saturday, July 5.

Dance star Fatboy Slim, real name Norman Cookand funk legend Bootsy Collins and dance giants Underworld will also be performing.

A festival spokesman said: "Hyde Park on Saturday, July 5, will be the place to be for anyone who loves to move to the music, whatever their chosen flavour."

US rockers Counting Crows will be joined by singer-songwriter Ben Harper and Australian rock group Powderfinger to round off the festival on Sunday, July 6.

Last year's little-known acts who appeared at the festival included Robyn, Kate Nashand Paolo Nutini, who have gone on to become household names.

Tickets for the festival are on sale now at a special 'early-bird' price of £40 for a limited period only. For more details go to
