The Northern Irish journalist said that the friendship between Holly and Alison was "nonsense" and "wouldn't have happened two years ago". See what he said in the video below.
"This other nonsense that goes on that Holly Willoughby now has Alison Hammond as her best friend and is at Alison's birthday party and Alison goes to Holly's select nights out with her friends," he said.
"This wouldn't have happened two years ago. Are you kidding? Alison Hammond has been on that programme for 13 years and I'm sure there was very little contact between her and the presenters. But then it all changed, people just use other people. It's disgusting and it's tolerated."
Alison and Holly have made no secret of their off-screen friendship. Back in August last year, Holly shared a touching tribute to the former Big Brother star after she was nominated for a National Television Award. Holly wrote: "There is only one @alisonhammond55… come on babe! This year is your year… congratulations… love you!!! #NTA."
Alison has made it clear that she'd love to be close with Holly's girl group, which includes Christine Lampard and Emma Bunton. Commenting on a selfie of Holly's friendship group which was posted to Instagram back in January, Alison wrote: "I want to be in this gang."
Holly was quick to respond, writing: "Any time babe," alongside a string of heart emojis.
Phillip Schofield's This Morning drama - the latest
Last Friday, Phillip Schofield admitted to an affair with a younger male colleague on This Morning and has now left ITV and been dropped by his talent agency YMU.
Phillip said he was "deeply sorry" for lying about the relationship to ITV, his colleagues, friends and agents.
"That relationship was unwise, but not illegal. It is now over," he said.
On Monday, Phillip hit back at critics and claimed that there was "no toxicity" on the show. "I hope you have noticed that it's the same handful of people with a grudge against me or the show who seem to have the loudest voice," he said.
The comments came after former This Morning resident doctor Dr Ranj Singh said the show had a "toxic" culture and that he was "managed out" after raising concerns about bullying and discrimination two years ago.
Elsewhere in Eamonn's interview with Dan Wootton, the broadcaster claimed that there was a "total cover-up" over Phillip's affair on This Morning.
"It's a total cover-up," he said.
"Those in authority had to know what was going on and they thought they would dodge a bullet with this which they do and they do constantly."
Referring to Phillip's latest comments denying any "toxicity" on the programme, Eammon went on to say: "I think that Phillip is absolutely right about toxicity.
"But my friend, the toxicity is not with me, Dan Wootton, or anyone else, the toxicity is with you."
