THE real Baby Reindeer stalker has branded Piers Morgan a “twerp” just hours before their highly-anticipated interview airs.
Fiona Harvey, 58, will be grilled by the TalkTV host, 59, in a tell-all telly exclusive tonight.
The gritty real-life drama was inspired by the ordeal suffered by Scots creator and leading man Richard Gadd, 34.
The then-struggling comic, while working in a London bar, hands Martha a free cup of tea before things turn sinister.
The series claims she subsequently bombarded the barman with more than 41,000 emails, hundreds of tweets and hours of voicemails over an alleged four year campaign of terror.
Now Harvey has vowed to tell her side of the story in a Piers Morgan Uncensored interview on YouTube at 8pm tonight.
But she took a swipe at The Sun columnist and former Britain’s Got Talent judge just hours before their chat is aired.
The real Baby Reindeer wrote online: “Piers is a twerp, but we already know this.
“You will see in my interview.”
Morgan said: “Reindeer breaks cover and gives me her first TV interview about the smash hit Netflix show.
“Fiona Harvey wants to have her say & ‘set the record straight.’
“Is she a psycho stalker? Find out tomorrow on Piers Morgan Uncensored.”
The trailer text for the interview reads: “The ‘real Martha’ from Baby Reindeer tomorrow on Piers Morgan Uncensored.
“sent from my ihphone.”
In Baby Reindeer, the misspelt “ihphone” for iPhone reveals that Martha is not actually emailing from an Apple device.
It comes after the Scottish Sun unmasked the curly-haired beak after she blasted Jessica Gunning’s portrayal of her saying she was “fat”.
We last month told how the Aberdeen University law graduate plans to sue the global streaming giant over how she is allegedly portrayed on screen by actress Jessica Gunning, 38.
Harvey told how she will represent herself in any legal action against the US-based broadcaster, vowing: “I will kick their a***s.”
Gadd, from Wormit, Fife, based his show on the “true story” of him being hounded by a punter he met while working in a London pub.
But Harvey, from Fyvie, Aberdeenshire, revealed she wants a court showdown after Baby Reindeer fans tracked her down and bombarded her with abuse online.
She told The Scottish Sun: “I have a claim against Netflix as this is being billed as part of a true story.
“There’s a fat actress that’s supposed to be me.
“I’m a highly competent lawyer. I’d have to do it myself. I’m very good.
“I have a photographic memory and can memorise huge files. I was top in my school at everything.
“People are probably saying I’m a mass murderer.
“This can’t continue. I will kick their a***s.”
