On Tuesday, the cast of "Riverdale" appeared on "The Tonight Show Starring Jimmy Fallon " to promote the show's upcoming season.

(Mark your calendars for October 11, y'all.)

After a sit-down chat with Fallon, Cole Sprouse, Madelaine Petsch, Camila Mendes, Lili Reinhart, and KJ Apa played a series of games, including the Milkshake Challenge and a "Family Feud"-inspired game against the Cyrus family.

There were plenty of opportunities for Sprouse and Reinhart — a rumored couple — to give fans the PDA they so desperately crave.

However, Sprouse and Reinhart went out of their way to avoid each other on-set. 

They didn't sit next to each other during the group interview. They didn't stand next to each other during the Search Party game. They didn't even slurp down their milkshake side-by-side.

Their distant body language *almost* had fans questioning the future of Sprousehart.

But alas, right as the show was about to cut to commercial, Sprouse walked over and embraced Reinhart.

Sprouse clearly thought the show had gone to commercial.

But nothing can escape the watchful eye of "Riverdale" stans.

Sprouse simply couldn't keep himself away from Reinhart, even for a few minutes.

Even when Sprouse and Reinhart try to hide their affection, it's so ~obvious~ that these two co-stars are a couple.

You can keep trying to fight it, Sprousehart, but your efforts cannot fool your fans.
