Darren Day has been charged with drink-driving after being arrested in Cardiff.
The actor and singer was apprehended by police in the early hours of the morning in the Welsh capital's city centre.
Day, 39, was taken into custody before being released on bail.
A spokeswoman for South Wales police confirmed: "A 39-year-old man was arrested in Custom House Street at around 02:00 BST yesterday.
"He was arrested and charged with drink-driving offences and was bailed to appear before Cardiff magistrates on July 2nd."
Day is currently starring in the musical Hello Dolly! alongside former Eastenders actress Anita Dobson at the city's New Theatre.
The I'm A Celebrity star's run in the show is scheduled to finish on Saturday.
Famed for his colourful love life - having dated and broken up with Anna Friel, Isla Fisher and Dancing On Ice winner Suzanne Shaw, with whom he has a son, Corey - Day recently gave an interview claiming to have reformed since his marriage a year ago.
"Life's very different for me now to what it was. I've landed on my feet really," he told the Western Mail newspaper.
"I married this wonderful lady and it's changed my life. She's pretty much 100 per cent responsible for changing my life around and my children have been inspirational too - life's fantastic."
