Nadia Essex is suing Eden Blackman.
The former "Celebs Go Dating" star - who was sacked from the programme for allegedly targeting her former co-star with cruel anonymous Twitter messages - claims she will face her nemesis in court next year over a string of allegations.
She told new! magazine: "It'll be next year. I'm suing for harassment, sex discrimination and victimisation."
And the 36-year-old star - who took herself to hospital after experiencing suicidal thoughts in the wake of the scandal - suggested Eden had had an affair with reality TV beauty Stephanie Pratt and vowed to tell all in court.
Asked if she thought they were more than friends, she said: "I think so. And when we go to court, we're going to stand there under oath and tell the truth of what happened.
"It's all going to come out under oath in court and then we'll see who's telling the truth."
But Nadia denied ever sending "trolling tweets", though she admitted she had done some wrong things.
She said: "I didn't send any trolling tweets.
"I didn't run around Twitter attacking random people and calling them a **** for no reason.
"I wasn't allowed to address his behaviour and I was getting abuse daily from people...
"I absolutely take responsibility for what I said - two wrongs don't make a right.
"I've taken responsibility for my mistakes and paid the highest price one could possibly pay and now it's a case of moving on with my life."
Nadia has accused Eden of making "constant digs" at her and refusing to sit in the same room as her, and she believes he acted the way he did towards her because he was jealous.
She explained: "Series one we were cool, everything changed the week the show came on telly. All of a sudden he stopped returning my calls and wouldn't return my messages.
"Straightaway I had my suspicions of why. Ultimately, he was mute in series one...
"He assumed he would be the lead presenter. I don't think he was very good at the job. I was good at the job and therefore got more camera time, which wasn't my choice, that's the edit.
"But I feel that he blamed me and resented me for that."
