It will be set about five years in the future, which means Josie will be in her early twenties, not still in high school.
President of The CW, Mark Pedowitz explained to TVLine, "Katy Keene actually takes place years after Riverdale High School. So, at the moment, there are no plans to do crossovers. And, if any of those Riverdale characters should come to Katy Keene, they will come as an older self."
Josie and Katy livin' it up in NYC!
Other cast members include Camille Hyde (American Vandal), Lucien Laviscount (Scream Queens) and Sterling Knight (17 Again).
