Here's one more reason to see Britney Spears' "Piece of Me" show in Las Vegas!
The pop star took to Instagram on Wednesday, where she shared a video of her rehearsing a new song for her show.
Check out the clip above to see which track Britt's rehearsing from her 2003 In The Zone album!
In the sneak peek, the 34-year-old shows off her toned tummy while rocking a white crop top and black sweatpants as she seductively dances to her early '00s single, "Breathe On Me."
"Just put your lips together and blow... #PieceOfMe," she captioned the clip.
