According to the Huffington Post, Britney Spears officially has her own holiday now, thanks to the city of Las Vegas. Because of her successful ongoing residency at Planet Hollywood, the Clark County commission chairman is honoring Spears with her own “Britney Day” on Nov. 5, along with a key to the Vegas strip. In the spirit of “Britney Day,” the “Toxic” singer will spend the day hanging with fans at the LINQ promenade. I wonder who else will be getting their own day next!
