Hellraiser Ozzy Osbourne was offered thousands of dollars by former GUNS N' ROSES guitarist Slash to strip off his underwear in front of British monarch Queen Elizabeth II.

The cheeky rocker admits he was tempted to accept the lucrative $8,800 (GBP5,000) offer to moon the royal when he performed in front of her at UK charity bash The Royal Variety performance in Cardiff, Wales, last month (NOV05).

But Osbourne admits that, since he quit drinking, he didn't have the courage to pull off such a rude stunt.

The 57-year-old tells The People newspaper, "A few beers inside me and I would have double-mooned the royal box.

"It was a surreal night."
