Solidifying her title as Las Vegas’s biggest star of the year with an elaborate event at The LINQ Promenade, tonight Planet Hollywood Resort & Casino headliner Britney Spears was presented with the Key to the City of Las Vegas’ iconic Strip by Clark County Commission Chairman Steve Sisolak, who also officially proclaimed Wednesday, Nov. 5 “Britney Day.” Additionally, Britney has announced new show dates for her massively successful Las Vegas resident show, “Britney: Piece of Me,” with tickets going on sale to the public Saturday, Nov. 8.

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. 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.

In the spirit of “Britney Day,” the legendary pop music icon celebrated with hundreds of her fellow “Britneys” (anyone named Britney with any type of spelling), who were invited to her “Britney: Piece of Me” show at Planet Hollywood Resort & Casino this evening. They also received a commemorative t-shirt, a complimentary ride on the High Roller and access to a priority area to view the event.

Britney also announced her partnership with Zappos and the Nevada Childhood Cancer Foundation (NCCF), where $1 of every ticket purchased to “Britney: Piece of Me” at Planet Hollywood Resort & Casino will be donated to NCCF.

"I am so proud to join forces with the Nevada Childhood Cancer Foundation and support children and their families in need in my second home of Las Vegas, Nevada," Britney said.

The NCCF is a local non-profit organization providing services in Southern Nevada since 1993, whose goal is to improve the quality of life for critically ill children and their families living in the community.

"We are thrilled that Britney Spears has chosen to partner with the Nevada Childhood Cancer Foundation with the support of Tony Hsieh and Zappos,” said Jeff Gordon, president and CEO of NCCF. “Britney brings with her so much passion for our cause and we feel privileged and honored to have her in our community and now as a part of the NCCF Family."
