Britney Spears bubble gum
Oops I did it again refers here to the time you bought another useless item online. This time it’s a piece of bubble gum the star chewed and spat out during a concert.
A woman saved this gum during a Britney Spears concert, and put it on auction. The winning lot was $14,000. This might seem crazy to you, but for those if us who grew up on her music, this is not something to be taken lightly.
