UPDATED! Britney Spears Kicks Off Piece Of Me In Las Vegas

December 27, 2013 By Jordan Miller

Britney went the extra mile once they turned the lights down at her grand opening of “Piece Of Me” in Las Vegas Friday night.

She performed for over 90-minutes for a crowd of 4500 in her newly renovated, state-of-the-art Axis theater inside Planet Hollywood. Before the show kicked off, media and celebs schmoozed upstairs at the pre-party and red carpet event. Celebs included Katy Perry, Miley Cyrus, Adam Lambert and Mario Lopez, all opting out of interviews, instead posing for photos on the red carpet before making their way to the show.

The energy was electric amongst the thousands of eager fans inside Axis, and Britney gave them a show to remember.

Watching the show from the VIP booths were Britney’s mother, father, sister, two sons and David Lucado. Seated next to the Spears fam were Sia, Selena Gomez, Katy Perry and Miley Cyrus – who twerked, danced and sang the entire show (she made out with one of Brit’s female dancers at one point, too).

As the Las Vegas Sun points out, Britney single handedly changed the scene on the Las Vegas strip, successfully performing an immense show inside a club-like venue.

Britney said in a recent interview she feels like her biggest competition is her younger self, but that insecurity was nowhere to be seen during the grand opening. She performed every song with conviction and vigor – “Slave” Britney would be very proud, as are her millions of adoring fans drooling over the footage seen on YouTube.

Joining her on-stage to play her boy toy during the “Freakshow” set was Mario Lopez, who frequently interviews Britney. He said of the experience: “That was a lot of fun and totally unexpected. I didn’t have a clue what was going to happen to me. I hope it all looked OK for the fun of it.”

Fifteen years in the biz and still a pioneer! Truly a monumental night for Britney, her fans and Las Vegas.
