However, if you did want to tally the pair's similarities and differences, Cole has you covered. In a new video for GQ's "Actually Me" series, Cole spills all the tea.
"[Our voice] is incredibly similar. Probably the most identical part about us," said Cole. "Except, for our nipple size, which is also exactly the same."
As for their differences? Well, Cole may be trolling us here (just guessing), but he has some thoughts.
"I am much more muscular than my brother and my jawline is much more strapping, which we all agree on."
Though Cole and Dylan may seem like a package deal, they've done their own things lately. Cole spends a lot of time in Vancouver, where they shoot his CW series, while Dylan and his girlfriend Barbara Palvin have just moved to their shared Brooklyn apartment. Palvin hasn't even met Cole yet!
"It would be super, super weird and totally not appropriate [for Dylan to be on Riverdale]. I also just don’t think Dylan wants to; to be honest, I wouldn’t want to either. People want to see us onscreen together again, and that’s fine. That’s flattering, I guess. But if it’s going to destroy the kind of world that we’ve built [on Riverdale], it’s wildly inappropriate."
Guess we'll have to find a new way to compare the Sprouse twins. Suite Life reruns, anyone?
