Wayne Carey’s ex-fiancee Kate Neilson has mocked the controversial AFL champion with a reenactment of the viral video that he denies was the aftermath of a toilet tryst.

In the video that began circulating last week, Carey was filmed putting his phone to ear as he emerged from the restrooms of a Melbourne bar just moments after a woman walked out.

Both Carey and the woman in the video, marketing executive Kate Aston, have slammed the people behind the camera and the sexual presumptions they triggered — suggestions the pair have both emphatically denied to be true.

But that hasn’t stopped Neilson, who had a rocky four-year relationship with Carey during the late 2000s, from poking fun at the man she was once engaged to marry.

The Australian actress and model posted a video of herself looking deliberately sheepish as she came out of a toilet, moments before her partner emerges from the same door and pretends to take a phone call.

The video was posted with a duck emoji in the bottom right corner. One of Carey’s nicknames is ‘Duck’.

It is also scored by the audio of Coldplay frontman Chris Martin’s reaction to the viral cheating scandal that his band inadvertently uncovered earlier this week.

Aston says her life has been suddenly turned “upside down” and her “suffering over recent days has been colossal”.

She has called the video a “deliberate act of bullying” and says she will now take legal action against the people who filmed it and made it public.

In the video, an unseen woman can be heard saying “she looks embarrassed” before someone else says “what’s he doing in there?”.

The relationship between Carey and Neilson is most infamous for an incident in the US in 2007 when Neilson suffered a bleeding lip after it was allegedly hit with glass.

Last November, she expressed her public disgust after Carey downplayed both the incident and their relationship.

Carey said on a podcast last year that it was “an incident with a girl that I was seeing on and off, I wouldn’t call her a girlfriend”.

“Wayne’s story about the glassing in Miami has again changed from when he did the Andrew Denton story (in 2008) saying he didn’t mean to break the glass on my face, but now he is saying he threw the glass on the ground,’’ Neilson fired back with last November.

“He was locked up in jail for a reason. Not because he poured wine on my face. I was bleeding profusely and the FBI took photos, which I have.

“So, to say I was hardly a girlfriend is insulting when I lived with him for years and he flew to Tasmania and met my family, wrote about my dad in his autobiography and I was engaged to him.

“I’m extremely insulted by the downplay of all of this.”

Carey has four children, two of which he shares with his current partner, Jessica Paulke.
