Some people mellow with age but Sinead O'Connor has become more daring, admitting she is determined to strip for Playboy magazine.
Unlikely centerfold Sinead, 45, hopes to make use of her outgoing nature now she's older, claiming she would never have shed her clothes at a younger age due to her sheltered upbringing.
Speaking to The Word magazine, she said: "There's so much I wouldn't liked to do (sic) when I was younger and I was too miserable and Irish.
"A Playboy shoot is on my bucket list. And I like the idea of doing some interview in weird sex gear, talking about something really serious. The economy! You can talk about serious issues while you're b**lock naked, on all fours, in your dog collar!"
The Nothing Compares 2 U singer has previously advertised for a sexual partner on the internet but, after a rocky start, her marriage to fourth husband Barry Herridge is back on track.
Unpredictable Sinead also admits she has to protect her 15-year-old daughter Roisin from her public antics.
She added: "I don't say it in front of her! She's worse than me anyway. She's determined to marry the singer from Muse, despite his being married to Kate Hudson. She has Muse carved into the side of her head."
