While the meaning of Cole's comment isn't exactly clear, we can appreciate the humour regardless.
Cole wasn't the only one to comment on the footage, with Skeet Ulrich - Jughead's on-screen daddio - commenting: "Wow!! Just like doing a scene with @instasuelos 😂," tagging Mark Consuelos, who plays Hiram Lodge.
KJ has always kept his romantic life tightly under wraps, however, back in July 22-year-old, KJ was snapped kissing his 29-year-old co-star Britt Robertson at the Entertainment Weekly's Comic-Con 2019 party in the US.
The two were spotted packing on the PDA while large crowds watched on, going as far as sharing a kiss, according to E! News.
The pair weren't shy in having their arms around one another while walking together around the event, even mingling with Riverdale co-star Camila Mendes at times.
So, does this mean Brit devours KJ Apa like a fly? Or the other way around...I guess we'll never know.
