A galaxy of stars are descending on Punchestown today to kick start the biggest festival of the summer.
Hailed as one of the best line-ups in years, final preparations have now completed for Oxegen 2010, with organisers gearing up to welcome in a string of big-name artists.
Top hotels in the capital city are bracing themselves for the arrival of the performers, with the Morrison, the Dylan and the Westbury expecting a deluge of famous faces.
Hip-hop king Jay Z has already jetted into Ireland via his customised Gulfstream jet ahead of his appearance on the main stage at the Kildare festival tonight night.
The star, who is famed for his love of the high life, is rumoured to have made some alcohol-related requests for his dressing room rider including plenty of red wine and spirits for him and his backstage crew.
However, he is not expected to stay for the weekend, given that he is also performing at T in the Park in Scotland this Sunday, as are several other Oxegen artists including Eminem and Muse. Other early arrivals include Canadian rockers Arcade Fire, Vampire Weekend, Groove Armada, Fatboy Slim and Stereophonics who will all open the festival to the 80,000 music fans, who have six stages to choose from this year.
Among those flying in to perform on Saturday night will be The Black Eyed Peas alongside Florence and The Machine, Calvin Harris, Dizzee Rascal and Kasabian.
One big draw for ticket holders is rapper Eminem, who will play the main stage on Sunday and has issued a request for a Playstation to be set up in his dressing room alongside some work out equipment.
The 8 Mile star was hit by false rumours this week suggesting that he could pull out of the Irish festival -- but organisers moved swiftly to deny this.
Meanwhile fans are being advised to pack their wellies this weekend, given that some rain is forecast.
