"How you guys feeling?" she asked the crowd at Planet Hollywood's Axis Theater. "It's been a while since I've been back so I think it's time to break the mother f---ing ice." She, of course, went into her song "Break The Ice."
Spears blew through songs like she ran through outfits. She came out in knee-high boots and a green bodysuit with a deep V-neck, showing off her cleavage.
She later showed off her midriff while donning green underwear and a shirt yellow shirt bearing the number 17 on the front. Again, she showed off her toned tummy. In the same outfit she seductively rode an over-sized mechanical guitar, as if it were a mechanical bull to "I Love Rock 'n' Roll."
Her most R-rated performance, though, was naturally saved for "I'm a Slave For You," in which she donned a tight black number that revealed her cleavage — all of this while she danced on a pole. (We wonder what Hillary Clinton, whom Spears met with in Sin City on Thursday, would think of that number.)
"It's hot in here. Are you guys hot," she asked the crowd following the song. As is a staple of the show, Spears then had her dancers pull someone from the audience to have them participate in the performance of "Freak Show."
"It's time for us to find a really hot guy, a really hot nerd," she said. "It's not about the sex, it's about stimulating our minds, right?"
After finding a man, she proceeded to make him get on all fours and walk. The "Freak Show" moment has been a centerpiece of her show since she first hit the Las Vegas stage in late December 2013.
Compared to previous incarnations of the show, the new outfits are unapologetically sexy … and so is her new show.
