‘Isolated’ Lisa Armstrong ‘no longer friends with Declan Donnelly’ after Ant McPartlin moves on with Anne-Marie Corbett

Lisa Armstrong has reportedly fallen out with Declan Donnelly and his wife Ali Astall following her split from Ant McPartlin.

The make-up artist, who is currently still married to McPartlin, has been left devastated by his new relationship with his PA Anne-Marie Corbett.

Armstrong is said to be feeling “isolated” and “angry” at the lack of support she has received from Donnelly and Astall.

“After knowing each other for so long Lisa felt that everyone had become friends in their own right – but obviously after what has gone on the divided loyalties have become obvious,” a source told The Sun.

“She’s really put out that Dec and Ali have totally sided with Ant over all of this. Even though Ant and Dec have always been best mates, she thought they would still remain close even after the split.”

The source continued: “In the end that just hasn’t happened – Lisa feels she’s been isolated by their former friendship circle and is pretty angry and upset about it.

“It’s yet another complication in a situation which has got extremely messy.”

Armstrong revealed to fans she has been left devastated by her husband’s new relationship, claiming she only found out when the news broke.

Responding to a Twitter follower who had said she “hoped he didn’t let you find out from the media”, Armstrong replied: “Nope. Just how you guys did.”

But she reportedly suspected the couple were dating months before the news broke after she saw pictures of McPartlin carrying a packed lunch, apparently prepared by Corbett.

She also liked a series of supportive tweets from fans branding McPartlin an “absolute scumbag” and his behaviour “abysmal”.

McPartlin is believed to have grown close to Corbett in the wake of his admission to rehab where he sought treatment following a drink-driving crash in March between the Mini he was driving and two other vehicles.

He was arrested and later fined £86,000 and banned from driving for 20 months.
