"I've been quarantined for five years now and that's OK, because all my favorite stuff is here," Fineman's Spears says, while rocking the heavy black eyeliner we've seen again and again in her Instagram videos and snapshots.
"Oops I burned my gym down," Spears sings, "so now I exercise outside! When I'm looking for a creative outlet, sometimes I'll paint, sometimes I'll pose. And I'm skinny as a needle!"
Throughout the fake ad, Fineman's Spears dances around her back yard, does yoga and lifts weights, in a variety of pastel (and astutely accurate) ensembles.
"The thing that helps me most in quarantine is being rich," Spears adds. "During this time of corona disease, we have to stay safe. My prayer is with you. I'm Britney Spears, and this is my master school."
The sketch also showcased Fineman's pitch perfect impression of Phoebe Waller-Bridge -- who teaches a Masterclass on "journaling" and Melissa Villasenior's incredible take on comedian John Mulany, who teaches a Masterclass on "suits."
