What's better than watching Fifth Harmony get their groove on? Watching Ellie Kemper join them!
On Friday, the pop group performed a few of their hits on Today's summer concert series — and, of course, they slayed!
Between sets, the Worth It quintet sat down with the Unbreakable Kimmy Schmidt star and revealed each of their favorite songs to perform.
They demonstrated their pre-show "booty popping" ceremony — and Kemper joined in the fun, too!
Check out the videos (below) to see the music group and the actress rocking out in the studio, and Fifth Harmony performing their hits Worth It and BO$!
