Chloe Madeley has been disqualified from driving for 20 months after pleading guilty to drink-driving.
The 22-year-old was arrested after a crash in Barnet, north London, early on August 16 after her car clipped another vehicle and overturned.
Hendon Magistrates’ Court heard that she had drunk two cocktails earlier in the evening and was almost twice the legal limit when the crash happened.
Ms Madeley had returned home after socialising with friends but left the house in her car because she “urgently required the services of a 24-hour chemist in relation to female products”, the court heard.
The judge ordered Madeley, the daughter of television presenters Richard Madeley and Judy Finnigan, to pay a total of £435, including £70 prosecution costs and £15 towards victims of crime, and told her the ban would start immediately.
Ms Madeley’s defence lawyer said: “She assisted the police fully. She feels dreadfully upset about what has happened, apologised to the police at the time and dealt with the accident appropriately.”
