Popsugar Celebrity Kj Apa KJ Apa and Casey Cott Troll Cole Sprouse and Lili Reinhart KJ Apa and Casey Cott Hilariously Trolled Cole Sprouse's Birthday Photo For Lili Reinhart 17 September 2018 by Karenna Meredith First Published: 15 September 2018 View this post on Instagram Both the birthday and my gift. My little muse, have a good day my love. A post shared by Casey Cott (@caseycott) on Sep 14, 2018 at 12:32pm PDT Nothing's safe from trolling when you're part of the Riverdale crew — not even relationships. Just a day after Cole Sprouse shared an intimate birthday post for Lili Reinhart, their costars KJ Apa and Casey Cott took it upon themselves to poke a little fun. Cole's original post showed a topless Lili, looking stunning as always, which he captioned "Both the birthday and the gift. My little muse, happy birthday my love." Freakin' precious, right? Well, KJ and Casey, ever the troublemakers, couldn't just leave this sweet and special moment in peace. No, naturally, they needed to try their hands at a spot-on re-creation. Casey shared a photo of KJ on Sept. 14, also topless, with the same caption. No harm in a little teasing, though! Lili and Cole both left comments on Casey's photo, and aren't afraid to throw in a little roasting of their own. Wonder if they're plotting a way to get their costars back? We know of a few KJ snaps that are just prime for re-creating.
