If you've ever watched Sex And The City (surely, that's all of us, right?), you may or may not have felt a pang of jealousy over just how close-knit characters Carrie Bradshaw, played by Sarah Jessica Parker, and Samantha Jones, brought to life by Kim Cattrall, are.
However, if Cattrall's latest Instagram post is anything to go by, their on-screen relationship was one that only lived on our TV screens, and certainly not in real life.
"I don't need your love or support at this tragic time @sarahjessicaparker," Cattrall wrote in response to SJP sending Cattrall her condolensces following the tragic passing of her brother, Chris.
"My Mom [sic] asked me today "When will that @sarahjessicaparker, that hypocrite, leave you alone?" Your continuous reaching out is a painful reminder of how cruel you really were then and now."
She continued: "Let me make this VERY clear. (If I haven't already) You are not my family. You are not my friend. So I'm writing to tell you one last time to stop exploiting our tragedy in order to restore your 'nice girl' persona."
So, what went wrong? When did this hostility actually start? And what fuelled it?
Well, THIS is everything we know so far…
