Britney Spears occupies a peerless place in pop, but even she's gotta keep things fresh.

The Britney Jean singer, who's been performing as part of a Las Vegas residency since 2013, is completely updating her "Piece of Me" show at the Axis at Planet Hollywood, and told Robin Leach for the Las Vegas Sun that fans should expect some big things for the big debut this weekend. First things first: She's now performing fan-favorite "Breathe On Me," which she said will bring a "very sexy vibe."

"I’ve added a few fan-favorite songs into the show, changed up the intro and had fabulous new costumes designed for each act," she said. "I also put together an amazing dance break to three of my favorite Missy Elliott songs.

One more thing:

"And we have lasers now. I love the look of the lasers."

And while B doesn't have any immediate plans for an expansive tour beyond Sin City, she said she's starting to crave the thrill of the road again, especially since she's begun to work on new music.

"I love doing my show in one place, plus it’s been great because I can have my boys out with me a lot of the time," she noted. "But, sometimes I do get that itch to travel and tour again. It’s in my blood."
