Sinead O'Connor, the troubled Irish singer-songwriter seems to want to 'reveal' more than just a piece of her bucket list. A Playboy shoot is on my bucket list, the singer told Word magazine. O'Connor doesn't seem to be comfortable being fully naked for the magazine though, as she told Word that she would like to pose in a dog collar.

The singer said that when she was younger she was too miserable to take her clothes off. No word if O'Connor barked her requests directly to Playboy, or if Hugh Hefner is interested in having 45-year-old O'Connor bare all.

Many celebrities have bucket lists, but none of them seem to top Sinead O'Connor's desire to pose naked with a dog collar for playboy. Country singer Carrie Underwood's bucket list is somewhat similar to Sinead O'Connor's in that she wants to get rid of something. For Underwood's case though it's not her clothes, but all her money. Before I die, I want to get rid of all my money, said the country star.

NASCAR driver Jeff Gordon told Sports Illustrated that he would love to go to the Monaco Grand Prix, Wimbeldon, and the World Cup. Probably at the top of the list is a professional soccer game in Europe, said the driver.

Matt Damon and Bill Clinton's bucket list could bring a tear to the eye. Damon said that raising my four girls to be strong, good women would be number one. Clinton expressed his bucket list desire, If I could have my wishes, I would like to live to see my own grandchildren.

What's on your bucket list?
