"I have always had issues with eating and I have always been very skinny," the blonde bombshell told Hit 107's Bec and Cosi. "A lot of people say I don't eat and I'm too skinny and that's the same as calling someone fat. It's so rude."
"I am on medication to help me eat and get my appetite back. It's due to stress and trauma I've been through," said Stacey who revealed during her honeymoon that her brother passed away on the same day she was due to give birth to her first child.
"I am in the process of gaining weight back because I'm on the scale of anorexic at the moment."
The news comes days after a report was published claiming Stacey hooked up with MAFS co-star, Mikey Pembroke.
The blonde later went on to deny the claims on KIIS FM's The Kyle And Jackie O Show.
"Mikey looks like my son, there's no way," Stacey told the radio hosts after refusing to join Michael on air. "He is not my type. What happened was I was in Adelaide when he hooked up with Hayley and no one told me what was going on and I was all alone.
"So Mikey reached out to me and asked to get coffee because he wanted to tell me what Michael was saying about me all night. It was nothing more than that," she insisted.
Stacey also denied the affair during a recent interview with New Idea, saying: "Nothing happened between Mikey Pembroke and I. No sexual relations. Nothing. I can guarantee that. And I can sit here and swear on anything.
“I understand where the rumours came from. We did share coffee and we did hang out. I swear that Mikey and I have never shared any sexual intimacy."
However, Mikey is sticking to his guns and maintaining they slept together.
“I can confirm we did have sex, but it was clearly after Natasha and I had agreed with producers that our relationship was over, and Natasha knew we weren’t together,” Mikey told News.com.au. “I actually didn’t want this (story) out as it’s not the best way to end my time on the show, but it did happen.”
