New Nickelodeon series Sam & Cat will feature a pint-sized British invasion in this Saturday’s episode. Sophia Grace Brownlee and Rosie McClelland, of viral video and The Ellen DeGeneres Show fame, guest star as two English girls whom Sam and Cat babysit. The girls at first appear sweet and well-behaved, but they end up being quite a handful because they’re actually con artists.
“Sophia Grace and Rosie are the most professional, incredible kids I’ve ever met,” Ariana Grande, who plays Cat, told EW. “It was kind of unreal, like, I was embarrassed. They knew their lines better than I did. They knew my lines better than I did.”
Grande also recalled how excited Brownlee and McClelland were to try on new dresses for a costume change and how well they knew TV set lingo: At one point, McClelland told the crew, “Just one more for safety, please!”
Below, check out an exclusive clip from this Saturday’s episode, called “#TheBritBrats.”
