Jamie Lynn Spears has brought footage of her mother, 'mawm dancing' - while seated in a car - to Britney's toxic. There are three important elements combined, which is probably why Lynne Spears looks so happy she could burst with sheer joy.

Not only does she get to mom dance, she also gets to combine it with seat dancing, AND it's to a song her daughter's singing. It's like every mother's trip to their child's Christmas panto, only on a bigger scale. And on Instagram.
