And the last photo Gum posted of the pair was back in January when they attended Cirque du Soleil.
Some fans were hopeful Skelton and her on-screen love interest Rankin might be a couple.
However, the pair are just colleagues and Rankin has even opened up in the past about how he likes to gross Skelton out before their kissing scenes.
He told Vanity Fair back in 2017: “The best thing to do before a kissing scene is to eat lobster or as much fish as you can cram in your face.
“That’s more interesting than a straight down the line kiss. Everyone’s doing normal kisses.
“The normal kiss is done, it’s so uninspiring. But if you’ve got a lobster tail hanging out the side of your mouth it’s much better.”
In response, Skelton quipped: “Any women trying to kiss Richard Rankin, there’s your warning right there.”
