TV dance judge Bruno Tonioli put the streak into Strictly - by stripping off for charity.
The BBC1 dance judge joined a host of celebrities including Strictly Come Dancing colleague Camilla Dallerup, Watchdog host Julia Bradbury and Apprentice star Kate Walsh to bare all.
Soccer star Sol Campbell also got his kit off for the Give Up Clothes for Good campaign, as did panto regular Christopher Biggins.
The stars posed for the saucy shots in a bid to get members of the public to strip their wardrobes to raise funds for Cancer Research UK.
Give Up Clothes for Good - which is supported by discount retailers TK Maxx and HomeSense - is a nationwide clothing and homeware collection scheme helping in the fight to beat childhood cancers.
The campaign, which launched yesterday and runs to April 25, has been held every other year since 2004.
In 2008 it raised £3.2 million worth of donations for the charity's life-saving research and this year aims to raise even more.
Ex-Atomic Kitten star Liz McLarnon, Channel 4's A Place In The Sun host Jasmine Harman, former EastEnders actress Lucy Benjamin, actor Jeremy Sheffield and cricketer Jimmy Anderson also shed their clothes for the cameras.
Tonioli said: "I really enjoyed taking part in this shoot and was glad to Give Up Clothes for Good to help Cancer Research UK beat childhood cancer. I hope everyone else feels the same and I encourage the nation to open up those closets; reach for those hidden marvels, and donate your fabulous items of clothing and homeware to TK Maxx and HomeSense stores."
BBC Countryfile presenter Bradbury said: "I had an absolute blast doing this shoot and am thrilled to help support such an important campaign."
Free donation bags will be available at branches of both stores, but all other bags are welcome.
Each filled bag could be worth up to £30 to the charity. Further details are at the TK Maxx website http://www.tkmaxx.com.
