Pop Star Britney Spears is currently in Las Vegas with her show Britney: Piece Of Me. Britney debuted her new show to multiple standing ovations and a star studded, sold-out crowd that included Katy Perry, Miley Cyrus, Selena Gomez, Kellen Lutz, Sia, DJ Pauly D, Serena Williams, Adam Lambert and Mario Lopez.

One look at the show and you can conveniently say that Britney has truly brought her most spectacular show ever to Las Vegas. A celebration of one of the most illustrious careers in music history, it is a compilation of more than twenty of Britney’s worldwide hits, including Baby One More Time, Oops I Did It Again, Toxic, Circus, Womanizer as well as some songs from her recently-released album Britney Jean.

Britney: Piece of Me is one of the most extravagant and mind boggling pop concert experience ever produced for Las Vegas, featuring a four piece band, fourteen dancers, elaborate sets, unforgettable costumes and state-of-the-art, never-before-seen technology. This extraordinary concert has been directed by one of the most sort after and respected creative directors for live Stage Entertainment, Baz Halpin.

Britney Spears is the first artist-in-residence to be housed in Planet Hollywood’s newly renovated The Axis Theater, which features one of the largest indoor video and projection installations in the world.

After watching the concert Miley Cyrus went on to host a party for Britney.

Miley Cyrus, who wore a scantily clad black and brown ensemble, was spotted having fun at the party and kept kissing and hugging anyone and everyone. Miley Cyrus was even spotted locking lips with a girl pal. Oops!!!

Kellen Lutz‘s attendance at the party raised some eyebrows, as he and Miley have been the center of romance rumors lately. The duo have been spotted spending time together in recent weeks and according to US Weekly report, they are having a fling.

Needless to say, just like the concert even the party was a rocking affair.
