The French DJ will be joined by fellow dance act Calvin Harris and US rapper Snoop Dogg.
Dublin band the Original Rudeboys, rapper Example and R'n'B star Pitbull have also been lined up for a bumper weekend of music.
Rock fans may well be disappointed by the line-up – what with recent years seeing hit bands such as Cold Play, the Killers and the Foo Fighters all taking to the main stages at the Kildare festival. UK rapper Labrinth and pop star Rita Ora are also on the bill.
International DJ David Guetta will be back in Ireland after playing at Dublin's Marlay Park last summer.
Ireland is a popular venue for the house music producer, who is sure to have fans bopping along to classic hits such as Sexy Chic, Titanium and Without You.
The festival is on during August 2, 3 and 4 – bank holiday week. Dance act Calvin Harris was the first act to be unveiled.
He will be joined by hip hop duo Rizzle Kicks. On Tuesday, rappers Pitbull and Example were also announced.
Example has become one of the UK's biggest rap sensations having sold out his recent arena tour of Ireland and the UK.
Award-winning DJs Jack Beats and Duke DuMont have also been announced to play the Kildare festival. They will be joined by DJ Fresh, Soul Wax, Nero, Nicky Romero, Sasha, Wretch 32, The Dead Presidents, John Gibbons, Devlin, Otto Knows, Iggy Izalea, Dimitri Vegas and Like Mike.
Tickets go on sale this Friday from Ticketmaster. Early bird prices for a three-day weekend camping ticket are €149.50, and a two-day weekend, non-camping ticket is €129.50. The early bird tickets are available for 24 hours only.
The popular festival was "rested" last year following the 2011 extravaganza with speculation that ticket sales were dwindling. The 2011 concert had a stellar line-up, with Beyonce, Coldplay, the Black Eyed Peas and the Foo Fighters all performing.
