Lili Reinhart and Cole Sprouse Just Got Hilariously Trolled by Their Riverdale Costars

That's a pretty solid burn.

Just a few short days ago, Riverdale's Cole Sprouse added more fuel to the are-they-or-aren't-they dating fire when he posted an artistically topless Instagram photo of co-star and rumored girlfriend Lili Reinhart to his account in celebration of her birthday. "Both the birthday and the gift. My little muse, happy birthday my love," he wrote in the caption. Reinhart seemed like she loved the picture—she dropped a heart emoji into the comments.

Although the photo was stunning, it also opened the rumored couple up to some pretty hilarious trolling by their friends and Riverdale costars.

On Friday, costar Casey Cott, who plays Kevin Keller, posted his own take on Sprouse's birthday present—only this time it starred KJ Apa. Cott and Apa even used the same caption as Sprouse, writing, "Both the birthday and my gift. My little muse, have a good day my love."

Thankfully, Reinhart found the entire thing to be hilarious, writing in a comment on Cott's post, "Show me those nips." (Apa also threw in a heart in the comments.)

Of course, she'd likely have to find this funny when you consider just how much her castmates love to poke fun at her and Sprouse on Instagram. In August, their other Riverdale pal Camila Mendes essentially confirmed their relationship by commenting on a meme saying "when you third wheel so much you basically become part of the relationship," which was posted by the aggregated account, @MyTherapistSays. In the comments, Mendes said, " @lilireinhart @colesprouse we're such a cute couple."

Though these coded messages could mean they are together, we might never know for sure: Reinhart has made it pretty clear in the past that her business isn't open to everyone's opinions.

"It’s horrifying how invested some people are in my love life. Emphasis on 'my.' It is mine. It is private," she wrote on Tumblr. "If a stranger's love life is causing you anger, frustration or anxiety…please reevaluate your priorities."

As long as the cast keeps the Instagram hilarity going, Sprouse and Reinhart keeping their relationship status private is OK with us.
