Brit-Brit has done it again. She's pulling out all the stops for her Las Vegas show Piece of Me. The recently renovated Planet Hollywood theater felt like a nightclub, with hard beats and lots of lasers.
The show features 21 songs, including hits from her first album, ...Baby One More Time, spanning her current album, Britney Jean.
Britney seemed pleased with her initial performance, taking to Twitter after the show to thank the audience for an amazing show.
And holy guacamole. Can we please talk about those abs?!
And of course, the audience was star-studded. Miley Cyrus and Katy Perry were among the most notable celebs, paying homage to their fellow songstress. Britney personally thanked each for attending via Twitter.
Miley sweetly tweeted, "if u told me I'd be front & center on @britneyspears opening night 10 years ago, I wouldve never believed you."
Later that evening, she was spotted at the opening of Beacher's Madhouse cozying up to Kellan Lutz, sparking more romantic rumors about the two stars.
Other star sightings at the show included Mario Lopez, DJ Pauly D, and Adam Lambert.
