Girls just want to have fun, y'all!

After burning through a poorly reviewed So-Cal mini-tour, Brit-Brit is getting back on the spangly performance wagon with a one-time appearance in Cyndi Lauper's "True Colors tour.

Spears will join Lauper's tour on June 30 in LA, and perform alongside Debbie Harry, Erasure and the Dresden Dolls.

Spears was supposed to audition dancers on Friday but never showed -- a good sign of the train wreck yet to come.
