The news comes after Bridges issued a statement last week after she was reportedly caught drink driving on Australia Day.
"I would like to express my deep regret for breaking the law, this was a terrible mistake and an error of judgment," she said
"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."
Bridges was pulled over in a 4WD in Sydney’s eastern suburbs around 11.25am on January 26 and taken to Waverley Police Station where she allegedly returned a blood alcohol reading of 0.086, making it a mid-range offence. She is due to appear in Waverley Local Court on February 18.
Bridges and Willis, 43, met as trainers on the weight-loss reality show in 2007 when they were both in relationships. They began dating six years later when both had separated from their partners.
