Paris Hilton made an appearance at E3 2006 to promote her game "Paris Hilton's Jewel Jam".
However, she didn't know the name of her own game that she was set to promote, and called it by a completely different name.
She was quoted as saying: "Sorry I'm late. I'm really excited to have my new video game, 'Diamondquest.' Thank you all for coming, and you can download the game."
In order to cover up her faux pas, the developers quickly changed the name to "Paris Hilton's Diamond Quest."
