Ant McPartlin has been charged with drink driving following a three-car crash in south-west London at the weekend.
The TV host, 42, was charged on Wednesday after he attended Kingston Police Station, with a group of people, understood to be members of his legal team.
Shortly after 5pm, McPartlin was pictured leaving his west London home.
It is understood he had several bags and suitcases with him and may have been leaving for rehab.
His co-host Declan Donnelly was then seen heading home after paying a visit to McPartlin.
Scotland Yard said in a statement: “A man has been charged following a road traffic collision in Lower Richmond Road, SW14. that occurred on Sunday, 18 March.
“Anthony McPartlin, 42, of Chiswick, has been charged by postal requisition on Wednesday, 21 March with drink driving.
“He will appear at Wimbledon Magistrates' Court on 4 April.”
McPartlin was pictured at the police station after spending several days holed up inside his house following his arrest at the weekend.
He earlier looked downcast as he stepped out of his home in west London, his first appearance in public after confirming he would be returning to rehab.
Representatives for the star announced he has terminated all work commitments for the "forseeable future".
ITV also revealed on Wednesday that Donnelly would be presenting Saturday Night Takeaway next week without McPartlin.
Donnelly will take the reins of the hugely popular entertainment show with co-stars Stephen Mulhern and Scarlett Moffatt also appearing as usual.
Donnelly said in a statement: "Whilst I never thought I’d be in this position, after much discussion and careful consideration we’ve decided that the remaining two shows of this series of Saturday Night Takeaway will go ahead.
"We made a promise to take hundreds of deserving winners to Florida to watch the series finale, and we will honour that.
"Everyone at ITV and the Takeaway team feels we owe it to the audience to complete the series."
An ITV spokesman said: "We can confirm that Saturday Night Takeaway, presented by Declan Donnelly, will return to ITV on March 31, and the series finale will be taking place at Universal Orlando Resort in Florida a week later."
