Olivia Attwood was left in tears after she was branded a "f***** crazy b****" by a dog walker.
The reality TV star was shaken by the confrontation, which she said was one of the "f***** up thing about being in this industry".
She tearfully documented her experience from her car, where she told fans that she felt "defenceless".
The Love Island star said that it was the first time she cried since leaving the I'm A Celebrity... Get Me Out Of Here! camp after she was forced to leave the show after a health check.
She was verbally assaulted by the woman as she took her Carpathian/German Shepherd mix Lola and her Rottweiler puppy Stitch, who she adopted with her fiance Bradley Dack.
Olivia told fans: "I can't believe I'm literally crying on my Stories but I literally just had the most awful experience. I've had the most awful experience, I literally can't believe what people are actually like.
"This is the first time I've cried in like, well since after the jungle, and before that was like two years so you know I literally never f****ng cry. I was just in the park with the dog and there was like a medium sized cockapoo and Lola went over to say hello and they were all wagging tails like no issues."
"I've never had an issue with my dog and another dog or a human ever, I've got like one of the best behaved dogs in the country. Like, she wouldn't be off the lead if she was a problem.
"And I was like walking over and as I walked over, the woman lunged in and picked up her dog for no reason," she continued.
She then said how the woman started to swear and shout at her in the park.
"Obviously it freaked Lola out so Lola obviously gives it a bark but didn't f****ng bite, didn't make any contact with the dog or the woman.

Olivia went on to say that she was called a "psycho" by the woman.
"She's saying I'm a psycho, like every expletive under the planet. But obviously because she screamed, and I've got a rescue dog, Lola was then like freaked out and then obviously, Lola was then like doing laps so I was trying to get hold of Lola and this woman was just like screaming," she said.
