After it found its way to the online marketplace in 2005, Britney Spears' pregnancy test raked in 5,001 dollars.
According to CNN, the positive test was found in a garbage can in a Los Angeles hotel room that the 34-year-old singer had stayed in with then husband Kevin Federline.
The test was bought by the Internet casino, which is known for bizarre celebrity merchandise purchases, from a Canadian radio station that had previously purchased the item.
