Kelly Osbourne is retiring at the age of 21.
The outspoken star - who shot to fame on hit reality TV show 'The Osbournes', with parents Sharon and Ozzy and brother Jack - admits she is sick of working.
Kelly has quit singing after just one album saying: "I don't intend to do anything. I've been working since I was 15 - what do I want to work for?"
Meanwhile, the young star's birthday bash ended in disaster after a massive pillow fight triggered the hotel's water sprinklers - flooding the building.
Kelly's 21st party on the ninth floor of the Las Vegas Hard Rock Hotel spun out of control when Paris Hilton's new boyfriend Stavros Niarchos reportedly sparked the play fight, according to America's Las Vegas Review-Journal newspaper.
But within minutes events turned sour when revellers began hurling furniture around. One guest then allegedly threw a table breaking the head of a sprinkler causing water to cascade into the rooms.
Fire alarms were then set off causing the entire hotel to be evacuated.
One guest revealed: "The carpet was coated with pillow feathers. Every lamp was broken. A maid told us they ruined every pillow in the room".
