Today, he has been ordered to pay what is believed to be the biggest ever drink-drive fine in Britain after he was caught more than double the legal limit in a auto crash.
After canceling an episode of "Saturday Night Takeaway" following McPartlin's arrest, ITV resumed the series for its final two installments - including a finale filmed at Universal Orlando in Florida - with McPartlin's co-host, Declan Donnelly, presenting solo for the first time.
One of the other drivers involved in the accident told the court that he and his wife "could have died" because of McPartlin's reckless driving, the BBC said.
It was in heard in court that the 42-year-old had been twice the legal drink drive limit when the incident happened.More news: Concluding ceremony of Commonwealth Games held at Gold Coast
Wearing a black three-piece suit, white shirt and black tie, McPartlin stood in the glass dock in court to confirm his name, date of birth, address and nationality before pleading guilty to driving with 75 microgrammes of alcohol in 100 millilitres of breath.
The driver of the Mini vehicle said afterwards, the court heard, that they thought they would die in the collision. The legal limit is 35 microgrammes.
'Higher standards are expected of me - I expect them of myself.
"I'm truly sorry for what happened". I let myself down, I let a lot of people down, for that I'm truly sorry. For that I'm truly sorry'.
At this point, Freeman was interrupted by the crash but - clearly a professional - she carried on, adding: "Excuse me, sorry, it's just some cars have had a bit of a crash behind us there".More news: Binghamton University freshman stabbed to death on campus, suspect at large
The statement said: "I appreciate people in the public eye should provide a positive example".
'I accept full culpability for this and wish to apologise to all those concerned'.
The TV presenter has been put off the road for 20 months and fined £86,000 after crashing in London last month.
