Sterling K. Brown Flossing on the Set of ‘The Marvelous Mrs. Maisel’

Sterling K. Brown has started filming for his role for Amazon’s Emmy-winning series “The Marvelous Mrs. Maisel” and he’s already flossing on set.

We have video of the “This Is Us” star during his first day on set Wednesday and he let loose during a break by busting out some sick dance moves.

Maybe it was first day jitters or he’s just that comfortable with the cast already.

Sterling K. Brown just announced he’s joining “The Marvelous Mrs. Maisel” cast for a three-episode arc this week, sharing a hilarious clip on Twitter. Announcing he’s “Eastward bound,” the two-time Emmy winner said he’s “going to do a little TV show, maybe you’ve heard of it … ‘The Marvelous Mrs. Maisel.'”

While details about Sterling K. Brown’s character remain under wraps for now, we can’t wait for him to join forces with Midge and Susie!
