Scarlett Johansson's used tissue is to be auctioned for charity.

The actress, who was plagued by a terrible cold when she appeared on US TV talk show "The Tonight Show with Jay Leno", left behind the tissue and now network NBC have decided to sell it on website eBay to raise money for food-gathering charity USA Harvest.

The actress is not the only famous face to have an unusual personal item sold on eBay.

Britney Spears' hair clippings - which were collected after she shaved her head in 2007 - and an empty can of Red Bull she had drunk out of attracted bids of over ￡500,000, but the site removed them before the sale could be completed.

Angelina Jolie's hairbrush has also made it onto the site, as did Heath Ledger's costume from cowboy movie "Brokeback Mountain".

A billiard table where Jude Law allegedly got intimate with his nanny has also appeared, as has debris from Shia LaBeouf's car crash earlier this year.

In 2006, a piece of gum chewed by Jessica Simpson just before she filmed a kissing scene with Dane Cook for movie "Employee of the Month" was listed.
