Sky Sports presenter Kirsty Gallacher was arrested on Saturday for driving under the influence of alcohol.
Police said the 41-year-old former Strictly Come Dancing contestant, from Virginia Water in Surrey, was arrested in Eton, Berkshire, on Saturday.
It is believed she was on her way to pick up her children from her ex husband Paul Sampson when she was pulled over and breathalysed, and was subsequently in custody at a station in Berkshire.
Thames Valley Police said Gallacher, 41, has been bailed to appear at Slough Magistrates' Court on September 4.
Kirsty had posted an image to Instagram of her enjoying a night out with three friends at the Winning Post pub near Winkfield on Friday night.

"You're a role model, you like it or not", she said of herself.
Kirsty, who briefly dated rugby star Danny Cipriani before striking up a romance with a mystery man this year, is considered a poster girl for Sky Sports News.
"But I still like to relax in the evening with a glass of wine".
"It's true! If I'm lucky enough to have one more then I'd be thrilled, as I don't feel like I have finished yet on the baby thing".
