David Guetta, Snoop Dogg and Rita Ora are among the headline acts added to the Oxegen bill for 2013.
The event, which looks set to become more of an electronic festival, had already confirmed Calvin Harris, Pitbull and Chase and Status for its August bank holiday switch for 2013.
Previously Oxegen (and its predeccesor, Witnness) had been a mix of rock, pop and dance acts with previous headliners invlusing Coldplay, Foo Fighters and Beyonce.
The event will take place at the Co. Kildare site from 2-4th August, with a capacity of 50,000, down from its peak of 80,000 in previous years.
