Britney Spears just can't stop being one of the coolest moms ever.

Having her own Las Vegas residency should say something about Spears' dance skills, but that didn't stop her from proving that she's got a few off-stage moves left up her sleeve.

WATCH: Britney Spears Pens Heartfelt Letter to Sons

The 34-year-old singer was hanging out with her sons, Sean and Jayden, in Malibu, California, on Saturday, when the crew paused to do the dab.

Spears was rocking a long-sleeve thermal shirt, dark skinny jeans and furry black boots when she and her boys, along with one of their pals, stopped to dance, shielding their faces from the camera.

Apparently Sean, 10, and Jayden, 9, have forgiven their mom for making goofy Instagram videos.
