Britney Spears is still a '00s girl at heart!
The pop star showed off her super tiny (and tanned) tummy as she hit up the mall with her boyfriend David Lucado in Los Angeles on Sunday.
Rocking a white crop top, a belly ring, shorts and a fedora, Spears looked happy and healthy as she engaged in some retail therapy.
The 32-year-old has been spending a ton of time in the gym lately and on stage in Las Vegas for her "Piece of Me" show -- and it's clear that all her hard work is definitely paying off. The "Toxic" singer's stomach looks just as toned now as it did ten years ago!
Check out the gallery above to see if other "TRL"-era pop stars have held up as well through the years!
