Ant McPartlin has been arrested on suspicion of drink-driving after smashing into two cars.

A girl of three was taken to hospital after the troubled I'm A Celebrity host, 42, lost control of his Mini with his mum inside.

The star, who is worth £60million, failed a roadside breathalyser test and was taken away by cops in the back of a police car for questioning.

The TV host lost control of his black Mini on a roundabout and went head-on into a green Mini containing a couple and their young child.

His car, with a distinctive double red stripe, hit a maroon BMW and ended upon the opposite side of the road.

Police confirmed he has been released under investigation on Monday morning after being held since Sunday afternoon.

His mum Christine and Labrador Hurley were in the car with him, and all three were said to be unhurt.

The child in the green Mini was taken to hospital and the girl’s mum appeared to have minor injuries, a witness said.

Amy Cassie, 23, who helped Ant's mum get the dog out of the car, said: “Ant seemed furious after crashing the car and was shouting at his mum who was also in the car. She was trying to get him to calm down.

She continued: “The police took him to the back of the police car to remove him from the situation.

“The couple in the green Mini were really shaken up and their child, who was a girl, could only have been about three years old.

“Ant and his mum didn’t seem to have any injuries, but the mum in the green car had split her lip and the side of her face was very red."

Police, paramedics and firefighters attended the scene in Mortlake, South West London, and the busy road was closed.

Ant’s mum Christine Woodhall returned to her son’s rented home in Chiswick, West London, yesterday.

A driver was seen collecting Hurley from the gated property at around 8pm.

The chocolate Labrador is thought to have been dropped off with Ant’s estranged wife Lisa Armstrong at their former marital home nearby.

It is not known what effect the arrest will have on ITV show Saturday Night Takeaway which he co-hosts with longtime TV partner Declan Donnelly, 42.

Ant, worth £60million, went into rehab last year after becoming hooked on painkillers.

He told how he became addicted to Tramadol after “botched” knee surgery two years ago left him in agony.

He also admitted drinking heavily and battling depression and anxiety. When he checked into rehab he said he had let “a lot of people down and for that I am truly sorry”.

He added last June: “I want to thank my wife, family and closest friends for helping me through this really difficult time.

“I’ve spoken out because I think it’s important that people ask for help if they’re going through a rough time and get the proper treatment to help their recovery.”

ITV stood by him last year and allowedhim “all the time in the world” to recover.

He was back on screen last autumn for I’m a Celebrity...Get Me Out of Here. Ant opened up about his drinking ahead of his stint in the jungle, but insisted he was not an alcoholic.

He said: “The great thing is I spoke to a lot of the medical team and I’m not an alcoholic. I was just drinking too much to numb the pain.

“It was never crazy — I wouldn’t wake up in the morning and have a drink. But it was the mixing pills with alcohol that was deadly.

“I’ve taken a little break from booze — I’ve done two months and I’ll do a little bit longer. But I’m looking forward to having a pint. God, yes!

“I can’t go to Australia and not have a cold one at the surf club with Dec like we normally do.

“That’s something to look forward to but I have to get well first.”

After two months in rehab, Ant claimed that he had “changed” and had even taken up yoga as he recovered from his ordeal.

He added: “I eat well. I’ve lost a stone. I can now do non-weight bearing stuff with my legs, like pilates, weights, lots of yoga, bike and stretching.

“I’m off everything now. Just your basic paracetamol and coping with the pain. I’m still in pain but managing it a lot better.”

But there was fresh heartache as his 11-year marriage hit the rocks and he split from wife Lisa, 41.

His spokesman said at the time: “In response to the recent speculation in the media, Ant is very sad to announce that, after 11 years, he is ending his marriage to Lisa McPartlin."

Lisa, make-up boss for BBC1’s Strictly Come Dancing, was said to have hired law firm Harbottle and Lewis to represent her in the divorce,according to reports.

Ant left rehab last August but never reunited with Lisa. Instead he moved into a £1.6millionrented house.

It was just a few streets away from the couple’s £6million West London mansion so that Ant could still be close to Hurley.

His mum has been staying with him as he adjusts to life after rehab.

Ant said of mum Christine last year :“She’s happy to have me back. People do notice the difference in you when you’re down and depressed. She noticed it. She said she’s really happy to have her old son back.”

Ant and Dec are arguably ITV’s biggest stars, and signed a three-year “golden handcuffs” deal with ITV which was thought to be worth £30million in 2016.

The duo were thought to have secured an increase of about 20% over the value of their last three-year deal, reportedly worth £25million.

By the time the current deal runs out in 2019, they will have been on the channel for 21 years.

The pair joined ITV in 1998, presenting Saturday morning shows SM:tv Live along with Cat Deeley, as well as CD:UK.

They met while working on the BBC children’s drama Byker Grove in 1989.
