They're never ever getting back together, you guys. Despite their claims that - in the wake of her split with husband Ryan Sweeting - Kaley and Johnny are just the best of friends. Friends who gnaw the necks off each other and then post it to Instagram. To be fair, this looks pretty damn sore!

Captioned "Hilarious night out in the LA Arts District w/ @normancook #BFFsbite @ludwig1965 @bricuoco", it has instigated such comments from their followers as "We are never, ever, eveeeeer getting back together.. ages later, hey you look edible..lemme bite you.. hmmm."

So when we said "biting each other's necks" it was more Johnny doing the biting. Kaley was more demure in her documenting of events, captioning this: "So fun tonight! #fallout4party @bricuoco @sanctionedjohnnygalecki."
