Did you know that Lilimar and Casey Simpson make a pretty amazing YouTube duo? The Nickelodeon stars from Bella and the Bulldogs and Nicky, Ricky, Dicky, & Dawn filmed an "Ask Casey and Lily" video together where they answered all kinds of fan questions sent in on Twitter.
TWIST made sure to tweet in a question to the actors, asking them to tell us all about their favorite costumes they've ever gotten to wear. Lilimar showed off a throwback pic of a Mad Hatter Halloween outfit while Casey revealed that he loved NRDD's Magnet Man costume!
