Oops ... she did it again! Britney Spears took to Instagram to release three videos of herself dancing in a black bikini.

And we have to say that the mother of two looks super fierce!

In all three videos, Britney dons a tiny black bikini and puts her best moves on display.

All the while, Nathaniel Rateliff & The Night Sweats' "S.O.B." plays in the background.

Brit Brit relaunches her show in Las Vegas in February, so maybe it's all related.

What are you up to, girl?
