Britney Spears is still the sultry pop princess she was 15 years ago.

On Monday, TMZ posted photos of the singer during her Las Vegas tour where she's been performing at Planet Hollywood. In fact, the site pointed out how there's a big difference in her wardrobe from what she's wearing now compared to before.

The difference is she's wearing less.

One shot shows Spears in a racy black one-piece outfit that exudes her strong legs and smooth skin down her back.

It was also revealed from Las Vegas Sun that Spears is debuting a new single called "Make Me (Oooh)." Depending on when exactly it gets released, perhaps, the star might be willing to perform it in an upcoming show.

And if things continue to run smoothly, then Spears might have another album following this single.

"I'm just particular with this record- it's my baby," the pop sensation said. "I'm proud of the work, and it's very different. It's not what you would think at all. I'm not rushing anything. I would much rather have it be completely how I want it to be. I just want it to be done right so that my fans will truly appreciate it."

Caesers Entertainment officials also dished on how successful the shows have been and how Spears is still keeping it sexy with her unique attire.

"It's stronger than ever at the box office," the statement reads. "They are the hottest, most colorful, most bejeweled outfits you've ever seen on a Las Vegas stage. If you thought they were sexy before this, then these are overdrive maximum sexy."

Spears' current run in Las Vegas ends on April 22, but she will be playing throughout the summertime. Tickets can be purchased here.
