I'm addicted to you, don't you know that you're toxic?!
"Toxic" by Britney Spears came out back in 2003, but it's still stuck in everyone's heads.
Jamie Lynn Spears Instagrammed a video of her mom Lynne Spears proving there's a third superstar of the Spears family.
Momma Spears is rocking out to Britney's TBT classic, putting her arms in the air and waving them around like she just don't care.
Fans took well to the dancing mom, with one commenting, "aw mama bear is proud."
