Sarah Ferguson was asked about her take on Prince Harry and Meghan Markle 's move to America as she joined Kate Garraway and Adil Ray on Good Morning Britain.
The Duchess of York, who has lived in America herself, was asked what she thought the late Princess Diana, who Fergie was close to, would think of Harry and Prince William' s current brotherly relationship.
She replied: "She was all about being true to her heart, and her heart would say, 'My boys have done really well, they look so happy in their own family units and they have beautiful children.'
"And that is what she'd look at. She'd look at altitude and I don't know, she's not here to speak for her self, but from me, if I'm here talking to you, I would say that we should have much more kindness in life."
"I think all of us need to stop being so cruel and trolling on the internet and social media. And, I think that we need to really lead by example, why don't you just smile and be kind?" Fergie added.
Meanwhile, the Duchess of York confirmed she will not be in attendance at the King's Coronation.
When asked if she'll be attending, she replied: "No I'm not because it's a state occasion and being divorced you can't have it both ways.
"I'm enjoying being divorced to my husband not from my husband."
Kate interjected: "You don't mind, you don't feel sorry? You have grown up with them and you're very close to Charles."
"The great thing about this moment in time is the unity of family I think they're doing a great job of unifying the family," Sarah continued.
The Duchess of York went on to say that although she may not be attending the Coronation, she still feels a "part of the family".
She added: "Just because I'm not there on the state occasion but in private I can be there and that's a lovely feeling to be part of the family, it really is. As I said you can't have it both ways, you mustn't sit on the fence – you're either in or out but don't muck around."
It's been confirmed Harry will be at the Coronation but his wife Meghan will stay behind in California with their two children Prince Archie and Princess Lilibet.
