Congratulations to the one and only Britney Spears after kicking off her two-year show "Britney: Piece Of Me" at Planet Hollywood Resort & Casino in Las Vegas this weekend! All of the rave reviews are showing that everyone still can't get enough of the Queen of Pop! 

On opening night, the 4,600-seat Axis Theater was packed with superfans including A-Listers like Selena Gomez, Katy Perry and Adam Lambert. Critics seemed to be huge fans of the show's amazing set production, dance numbers, and all of the (very heavy) bedazzled constumes Brit changes into throughout her sets.

Miley Cyrus also tweeted a pic from front row & center raving that Britney looked 'BANGIN!' She was close enough to dance along with Britney during the performance of 'Til The World Ends' - watch the pop divas rock out together in this Insta-video that went viral! 

Check out the buzz about the show!
