Speaking to new! magazine about Harry and Meghan's approach towards Thomas Markle, the former butler said: "I've been in similar situations where people said things about Princess Diana, and the way she dealt with it was by freezing them out.
"It looks as if Harry has taken a leaf out of his mother's book. Diana said, 'Once someone burns the bridge of trust towards you it's very hard to repair it.'"
He added: "Harry is his mother's son and the apple doesn't fall far from the tree...
"She would be furious if someone betrayed her and the only way she could deal with it is to cut them off completely".
It comes after he previously commented on how Meghan might have longed for the fame that her new role has brought her, but that she should "be careful what she wishes for" as "sometimes it is not all that it seems".
In the interview for Yahoo News weekly six-part series, he also weighed in on the Royal Family's treatment of Thomas Markle, saying there is "no protocol" for dealing with in-laws.
Burrell said: "Poor Thomas Markle doesn't know how to behave, he is lost.
"I think the best thing he could do is stay quiet and try and reach out to his daughter. Somebody has to fix it. Before it gets more broken.
"Thankfully Meghan's mother has survived with dignity and style and that's the way forward."
The former butler also urged Meghan to "get on with" having a baby, describing how "time is marching on", and predicted that the duchess would fall pregnant in her first year of marriage.
