The Geordie star was once one of the most respected presenters in the business along with his hosting partner Declan Donnelly.
Now after two stints in rehab, a drunken car crash and an appearance in court, Ant’s reputation is in tatters.
To make matters worse, ex wife Lisa has started to tweet about her heartbreak after months of silence.
The tipping point was when the successful make-up artist discovered Ant is now in a relationship with their PA Anne-Marie Corbett.
Now Daily Mail columnist Jan Moir has savaged the 11-year-marriage – claiming Lisa was more of a plus one than a wife.
“Something for all those little Cinderellas to remember, as they plot and dream of marrying a rich and famous Prince Charming. When it is over, everything is over”
Jan vented: “Marriage is hard enough, but marriage to a star when you are not one yourself?
“Well, that is a nightmare, especially when good love goes bad.
“For the perils of what you might call a Plus One relationship (where you are always the ‘plus one’ on a star’s invitation) mean you are forever in their shadow, the afterthought, the overlooked.
“The scales of power are tipped, but never in your favour.
“Lisa knew and loved Ant long before he was one of the highest-paid and most popular television stars in the UK.
“The pair of them were grounded, they grew together — but fame changes people. They become more demanding, more self-centred, used to the attention.”
Going on to claim Lisa has been left ostracised and alone, Jan added: “To make matters even worse, according to reports, Lisa has been excised from their mutual circle of friends, including Declan Donnelly and his wife.
“That is what happens with Plus Ones — they have no power, they are struck off the guest list for ever, cast out into the ‘civilian’ wilderness.
“Something for all those little Cinderellas to remember, as they plot and dream of marrying a rich and famous Prince Charming. When it is over, everything is over.”
Lisa is currently in Los Angeles trying to keep away from the press and new revelations about her former husband.
While the divorce is still ongoing, the Strictly worker has finally removed a picture of her Ant and their dog Hurley from her Twitter banner.
Instead she’s tellingly replaced it with a similar picture of just her and Hurley.
