The TV host's publicist has confirmed in a statement that Ant, 42, is heading back to rehab as the ITV show is cancelled for this weekend. He was arrested for suspected drink-driving after he failed a breathalyser upon the arrival of police.
Christine was travelling with Ant and his dog, Hurley, when they were involved in a three-car smash when Ant's Mini allegedly exited a roundabout and ended up on the wrong side of the road.
Saturday Night Takeaway is sponsored by Suzuki in a £20million deal and Ant and sidekick Dec are also paid to appear in adverts for the auto maker.
A police spokesman said: 'A 42-year-old man was arrested at the scene on suspicion of drink-driving after failing a roadside breathalyser test.
Amy Cassie, 23, who said she witnessed the crash, told the Mirror: "Ant seemed furious after crashing the auto and was shouting at his mum who was also in the vehicle".
"We very much hope that he gets the help that he needs".
GETTY SUCCESS Ant and Dec won numerous awards at the National Television Awards in January
We reported how Ant was "agitated and argumentative" with a policewoman as she arrested him.
"He has spoken with Dec and ITV today and asked for time off for the foreseeable future".
Police have said that a number of people were treated at the scene for minor injuries and that the child passenger from one of the cars was taken to hospital for a check-up as a precaution.
It's not known how long Ant will be in treatment, or when Saturday Night Takeaway will return to screens.
In January, he announced he was divorcing wife and Strictly Come Dancing make-up boss Lisa Armstrong after 11 years of marriage.
Ant underwent treatment for prescription drug and alcohol addiction last summer, and has once again checked into a treatment facility.
