We've already had a wild cousin twist on Riverdale, with the Blossoms being related to the Cooper family... however, could the Andrews' also be involved in this messed up family tree?
Well, Riverdale red-heads Madelaine Petsch (Cheryl Blossom) and KJ Apa (Archie Andrews) have spoken to Glamour about that possibility.
"I've wondered that before," revealed KJ.
However, Madelaine wasn't so much on board with the theory. "I personally think no. I know plenty of other red heads that I'm not related to personally, that I grew up with," she explained.
"But you never know," she added. "It's Riverdale. My whole theory now is it's Riverdale. Anything can happen."
True that Madz. Your brother did get his cousin pregnant after all...
