And it's all because of the most bizarre reason...
Yep, we're not even joking.
You might also remember Cole and Dylan from when they worked together on The Suite Life Of Zack & Cody.
Cole Sprouse (who plays Jughead Jones on Netflix's Riverdale) won't let his brother Dylan watch Riverdale for the weirdest reason.
Speaking exclusively with Elle Magazine, Cole said he'd prefer that his twin brother "doesn't" watch the series.
"He supports the show…. I don't know if he enjoys it," he explained.
"This kind of programming has never really been our flavour of choice. I don't really want him to watch anything I do and I don't really watch anything he'll do."
Ummmmm, what does that even mean??
He then added that the reasoning might have more to do with the fact that he really struggles to watch himself on TV.
"I don't really have an easy time watching myself, so I guess I sort of imprint that upon my friends and family," he admitted.
