"Girls just wanna have fun," Spears teased with a winky face in her caption. "Never released a video for this song... so decided to do a little tease on Instagram instead... enjoy!!"

PICS: Britney Spears Through the Years 

The track was featured on Spears 2003 album, In the Zone, but was never released as an official single. As a re-vamped version of the singer's Piece of Me residency show in Las Vegas kicked off at Planet Hollywood last week, Spears managed to find a new place for the fan-favorite tune on her set list.

It's no surprise that Spears' body looks incredible -- she's hardly been shy about showing off those abs -- but that colorful ink on her side and thigh definitely appear to be new.

Are the tatts permanent? Probably not, but they sure look fun!

Now, watch the video below to find out why Spears was looking for a well-endowed "hot nerd" during a recent performance.
