The 32-year-old singer shocked the world with the famous "Oops! ... I Did It Again" striptease she performed during the 2000 MTV Video Music Awards, and 13 years later she decided to perform it again in her iconic look during the second night of her new Las Vegas residency.
Spears wore a glittery nude crop top and matching tights during Saturday's show.
The mother of two is expected to recreate several of her most famous looks for her Piece of Me shows, which will take place at Planet Hollywood in Las Vegas over the course of the next two years.
Spears will do about 50 shows a year during her Vegas residency.
