“Well, I first met her at Peter and Autumn’s wedding and again it was amongst a lot of other guests, and she was very friendly,” Kate Middleton had then said.

“She knew it was a big day and everything was going on with Peter and Autumn. She had wanted to meet Kate for a while, so it was very nice for her to come over and say hello. We had a little chat and got on very well," Prince William had said on Kate Middleton's meeting with Queen Elizabeth II.

A royal family expert says Kate was reportedly fighting back tears after she recently encountered a reminder of the late monarch. Here’s what the expert says caused the Princess of Wales to become emotional.

Royal expert Neil Sean said that Queen Elizabeth II saw Kate Middleton as a trusted friend.

“She said that Her Majesty the Queen not only was just a wonderful lady but also a very good friend, a confidant,” Neil Sean said.

“[She was] someone she could really rely on and chat to at any given moment when she was having serious moments of doubt, as I’m sure she would be in such a big role," the expert added.

Kate Middleton became emotional after walking into a room and smelling Queen Elizabeth’s perfume, the royal expert claimed.

“She told a source that it’s this one thing that could trigger literally tears and indeed happy memories, but bittersweet memories, was the smell of the former monarch’s [perfume]," Neil Sean said.
