Britney Spears joined Jimmy Fallon for a totally ahmazeng instalment of recurring Tonight Show sketch "Ew," on Thursday.
Reuniting for a sleepover after meeting at camp, Sara (Fallon) and her BFF Abby (Spears) obsessed over horses and custom mermaid pillows, traded Throwback Thursday Instagram photos, and nailed Fashion Freeze.
There's a perfect "I'm Not a Girl, Not Yet a Woman" throwback, plus, they totally gave mad love to Steve Carell in here, especially for his work in Dahspackabal Mah Thrah.
