Ozzy Osbourne felt "excited" being in New York during 9/11.

He told Shortlist magazine: "I wasn't scared, I was excited! It was my kind of craziness, y'know.

"The day after that happened, there was f***ing nobody in New York. I remember standing on the steps of the hotel, and - you know when you see an old cowboy film and that tumbleweed rolls past on the ground? There were newspapers just floating around on the streets. It was so f***ing weird."

While the Black Sabbath frontman wasn't frightened by the incident, he admits being anxious over the current unrest in the Islamic State of Iraq and Syria (ISIS) and is expecting a lot of the human race to be wiped out with a nuclear weapon sooner or later.

He explained: "I hope this ISIS lot don't get going. I've come to the conclusion that it's in mankind to try to kill each other for one thing or another.

"I think sooner or later one of these crazy f***ers is going to get a nuclear weapon or some f***ing thing, and f**k a lot of people up. That's in our nature."

The rocker - who is married to former 'X Factor' judge Sharon Osbourne - also revealed he once drank three bottles of wine before attending a Correspondents' Dinner at the White House, where he was a guest of honour, and thought the then-president George W. Bush was a "****".

He said: "He was a ****. I was f***ing faced at that dinner. I'd had three bottles of wine before I went in there. Sharon was going f***ing nuts at me.

"No one would come near me because I was off me f***ing nuts.

"I've met him, I've met Bill Clinton, I've met loads of them but they're very strange people.

"Hilary Clinton was wonderful, a very nice lady. George Bush, I never quite got his deal."
