Michelle Bridges and Steve "Commando" Willis have officially split.
The 49-year-old confirmed the break-up in a statement to The Daily Telegraph after being caught drink-driving on Australia Day while the former couple's four-year-old son Axel was in the car with her.
"I would like to express my deep regret for breaking the law, this was a terrible mistake and an error of judgment," Michelle said in a statement obtained by the publication.
"This behaviour is inexcusable, and I am absolutely devastated and embarrassed to find myself in this position.
"It has been a very difficult time for me the last few weeks dealing with the break-up of my long-term relationship. This is by no means an excuse for my behaviour but I feel the emotional turmoil I have been going through has impacted my decision making. I am extremely sorry for my actions."

Rumours have long been swirling that the pair were headed for a bust up, with an inside source telling Woman's Day last year that Steve, 43, and Michelle were leading increasingly separate lives following a series of explosive arguments.
"The relationship has become increasingly toxic in the past 12 months," revealed one close friend in May 2019.
"They are constantly bickering over everything, from work to parenting to what to have for dinner. His daughter Brianna was living with them for a while, but she found the arguments so unbearable she moved out."
Speaking to Now To Love in September last year, Michelle explained how she and Steve dealt with stressful family moments.
"We pick up on each other's vibes on what's happening at any given moment so sometimes he'll just go and do a workout or I'll be like, 'You know what, go do your thing,'" Michelle said.
"I think in any relationship you have to be able to read each other and give the other person that space that they might need and if you're the one kind of giving them the space, you kind of know that eventually one way or another that it'll come back to you. So it's that swings and roundabouts scenario."
Michelle and Steve went public with their relationship in 2013, after falling in love on weight loss reality show The Biggest Loser, where they both worked as trainers.
At the time, Michelle broke up with her husband of nine years, Bill Moore, within weeks of The Commando separating from his de-facto wife of seven years, Froso.
As well as son Axel, who he shares with Michelle, Steve has three other children from previous relationships: Brianna, 19, Ella, 11 and Jack seven.
