November 5 will now forever live in infamy as Britney Day (bitch)! Yesterday our favorite pop queen Britney Spears celebrated the new holiday named in her honor, where she was presented with the key to the City of Las Vegas.

During the Spears-centric event—which took place at the at the LINQ Promenade smack in the center of the Las Vegas Strip—the singing sensation (who looked gorgeous in a sparkling black ensemble) was surrounded by her family and tons of adoring fans (pictured above). The festivities included a parade of showgirls, an official proclamation of Britney Day, and ended with Spears being given the key to Las Vegas by Clark County Commissioner Steve Sisolak and Planet Hollywood regional president David Hoenemeyer (pictured below).

To top it all off, Spears also announced that she is adding additional dates to her Planet Hollywood residency. How's that for exciting news, Britney fans?
