Holly and Phillip’s working relationship came to a shock end in May after he admitted to lying to her and show bosses about a six-month affair with a much younger male colleague.
It was recently confirmed that Holly has been complying with an independent investigation into the scandal.
And now Phil has removed all traces of her from his social media.
His Instagram page once proudly displayed snaps of the former colleagues hosting This Morning and on holiday together.
A source told MailOnline: “Holly and Phil used to post pictures together for fun, they were huge parts of one another’s lives and they loved to show their viewers how close they are.
“The fact that Phil appears to have removed them from his page is very telling about how he feels about Holly.
“He seems to have moved on for good now, and is trying to leave Holly behind.”
It comes after Phil unfollowed Holly on Instagram earlier this month, ahead of the National Television Awards – which his name was removed from.
Holly is still following Phil on social media
In his first interview after the scandal came to light, Philip exclusively told us how he had not had any contact with Holly since the news broke.
He told us: “I’ve lost my best friend. I let her down (Holly). I let that entire show down. I let the viewers down.
“Holly did not know (about the romance). And she was one of the first texts that I sent, to say, ‘I am so, so sorry that I lied to you’.
“She didn’t reply and I understand why she didn’t reply, as well. So yeah. If anyone is in any way linking Holly to this; that is absolutely, wholly untrue.
“I had no feud with Holly. She is my TV sister. But quite rightly, when I am in the middle of a s**t show with bad press over something where I have done nothing wrong — in fact, I did everything right — it’s a witch hunt. And that strips that (friendship) away.
“Quite rightly, she is going to take a step back and think, ‘I have to step back from this’, and I understand that completely.
“As we see now, this is a vicious game and the last thing you want is for something to stick on you.
“It was becoming bigger than the people we had on the show. I understand that.”
