Kirsty Gallacher has divulged that she was reeling from her divorce to rugby player Paul Sampson, the father of her two children, when she was arrested for drink driving.
The presenter was banned from driving for two years in 2017 after being found to be nearly three times over the legal limit following her arrest in the August of that year.
She told The Mail on Sunday's You magazine: "I was in a very bad place with the divorce and issues to do with the children’s schedule. I was exhausted."
Gallacher, 43, was pulled over by the police after picking up her car from a pub the morning after a night of drinking.
She was found to have been “driving erratically” when approached by police on Eton High Street in Berkshire.
The mother-of-two shared: "I wasn't thinking straight. It was very bad and very un-Kirsty because I've always been a good girl.
"We all make mistakes, life's not perfect. And in the limelight you're apparently not able to put a foot wrong."
While Gallacher had originally been given a two-year ban from driving, the term was reduced to 18 months after she attended a driving rehab course.
In addition to the ban, Gallacher was also instructed to do 100 hours of unpaid community work and pay a £85 fine.
She split with former husband Sampson, 42, with whom she shares two sons, Oscar, 12, and Jude, nine, in 2014.
It came just a year after her father, golfer Bernard Gallacher, suffered a serious cardiac arrest where his heart stopped repeatedly, although he did survive.
