Public fascination with celebrity has been a constant for thousands of years. From martyrs' relics to One Directioner Neil Horan's half eaten toast, people have always loved to collect intimate, and often gross, items from their favourite figures.
Below are five of the biggest sales of celebrity leftovers.
5. Justin Timberlake's French toast - $1,025
Back in 2000 a piece of Justin Timberlake's half eaten French toast was sold to a rabid N'Sync fan on eBay for $1,025. It was consigned by New York's Z-100 radio station, who donated the proceeds to charity.
The winner told the press that she would "probably freeze-dry it, then seal it...then put it on my dresser".
4. Kate Garraway's banana - $2,746
In 2004, a banana signed by British GMTV and Daybreak presenter Kate Garraway sold for an impressive ?�1,650 ($2,746) in an eBay charity auction.
Screentrade, an insurance firm, were the winners of the auction.
A spokesperson for the firm commented: "We thought it might generate a bit more fun around the office. It might be exhibited in our reception area."
3. Prince William and Kate Middleton wedding cake - $4,160
A piece of Prince William and Kate Middleton's wedding cake sold for ?�1,917 ($3,191) at PFC Auctions in 2012. Pieces of cake are traditionally given as gifts after royal weddings, but only to the selected few chosen to attend - 650 were given out after the Duke and Duchess of Cambridge's wedding, with many more left hungry.
In 2012, our own PFC Auctions sold a piece from Charles and Diana's wedding in 1981 for ?�1,757 ($2,914).
2. Britney Spears chewing gum - $14,000
A piece of gum that Britney Spears spat out at a show allegedly sold for $14,000 on eBay in 2004.
While it's unclear as to whether the sale was finalised, Spears is a compulsive masticator and pieces of her old gum regularly sell for hundreds of dollars on the site.
1. Niall Horan's toast - $100,000
While on an Australian morning TV show, One Direction's Niall Horan was offered a piece of toast slathered with Vegemite - the nation's favourite spread.
Unfortunately Horan wasn't keen on the taste and promptly spat it out. In the aftermath the remains of the toast were collected and placed on eBay - with the proceeds intended for charity.
The notes read: "The item is perishable and although we will package it so that tampering is evident, we do not advise that it is consumed. We will not be including the mouthful that Niall spat out - because that's just gross."
Bidding reached an incredible $100,000, although the sale was never confirmed.
