Britney Spears presented with the key to the city in Las Vegas

LAS VEGAS, Nov. 6 (UPI) -- Pop star Britney Spears has been presented with the key to the city of Las Vegas' legendary Strip by Clark County Commission Chairman Steve Sisolak.

Wednesday was officially proclaimed "Britney Day" in the Grammy Award-winning singer's honor.

As part of the festivities, Spears also announced 36 additional dates for her hit Las Vegas resident show Britney: Piece of Me at Planet Hollywood Resort & Casino. She began the string of performances at the venue last December.

"With a bit of feathers, rhinestones and Sin City flare, authentic Las Vegas showgirls from Jubilee at Bally's Las Vegas performed a Britney-inspired number to the international superstar's chart-topping hit 'Toxic' on The LINQ Promenade Fountain stage," a news release said. "To the crowd's delight, the beautiful, long-legged showgirls revealed the one and only pop icon with their iconic feathered fans at the end of their performance."
