It was reported in the Sun on Sunday that the 42-year-old TV star had struck up a new romance with assistant Anne-Marie Corbett who helped “put him back together again” amid recent drink-driving woes.
According to the newspaper Ant and Ms Corbett, who herself split with her husband in October, grew closer during his rehab time for alcohol addiction and drink-driving court case.
Lisa Armstrong, Ant’s wife of 11 years, criticised Anne-Marie on Twitter in a series of posts after the reports emerged, accusing her of breaking "girl code" by dating the troubled presenter.
Ant's new relationship appeared to have left the 42-year-old make-up artist heartbroken as she tweeted several broken heart emojis, sharing her sadness, shortly after the news first broke.

Lisa then revealed she did not know about the romance and only found out after reading about the new relationship in the media.
Responding to a Twitter follower who had said she "hoped he didn't let you find out from the media", Lisa wrote: "Nope. Just how you guys did."

She then received a message of support from TV personality Nicola McLean. "Sending my love Lisa! Really feel for you worst pain ever," Ms McLean said.
Lisa replied: "Thanks babe and to think she was MY friend."

The MailOnline reports another follower said "so much for the girl code", to which Lisa replied: "Exactly!"
The make-up artist then replied to another tweet to say that Anne-Marie was her friend and the couple's PA, adding that she let her "into our home".
Yeah My Friend and OUR Pa who I let into OUR home. 💔 https://t.co/1eMqN4mjyu— Lisa Armstrong (@lisaAmakeup) June 17, 2018
Ant and Lisa, a 42-year-old make-up artist, announced in January that they were separating.
Two months later, Ant was arrested for drink-driving following a collision in south London. No one was hurt in the collision but the I’m A Celebrity presenter was fined £86,000 and given a 20-month road ban.
Since then the star has stayed out of the limelight and sought help from a rehab clinic.
But it was reported on Sunday that he had moved on with Ms Corbett after she had supported him through the troubled months since the collision.
The pair are said to have grown close since his split from Lisa, with sources saying Ms Corbett had been Ant’s “rock” during the difficult time.
A source told the newspaper: “Anne-Marie’s put him back together again. Everyone’s thrilled he’s found someone to love.
“She has been his rock. They have been living in each other’s pockets, day in, day out. Knowing someone is there for him has brought him back from the brink.
“It’s very early days, but everyone is hoping he can put the worst year of his life behind him and find happiness again. Both of them deserve it.
“Since he has come out of rehab, Ant can’t really go out socialising, to restaurants or anything like that. It means he has spent an awful lot of time with her and has realised she’s the one for him.”
Following Lisa’s tweet, caring fans sent reassuring messages to her telling her to “hold your head up high” and praising her “respect and dignity”.
You are an extremely dignified and a woman of high class. You have been respectful throughout and although you are getting divorced, it’s disappointing you have not been afforded the same dignity and courtesy back. You have my utmost respect and love xxxxx— Rebecca (@beckie20) June 17, 2018
Morning Lisa, read it this morning & instantly thought of you. Hold your head up high, you’ve done amazing throughout everything & really are the better person😘— HomeEdFamily (@AlisonHatcher3) June 17, 2018
“You’re one of the most beautiful, strong courageous women, who deserves so much love,” one wrote.
“The way you’ve held your head high and been so dignified is inspiring to women everywhere.”
