The public appearances come hours after her grandson Prince Harry's Apple TV+ series on mental health dropped online.
The new docuseries, called The Me You Can't See, saw the royal address traumatic memories from his childhood, including the death of his mother Princess Diana and harassment on social media of he and his wife Meghan.
The Duke of Sussex also told host Oprah Winfrey his family did not speak about Diana's death and expected him to just deal with the resulting press attention and mental distress.

The series comes just weeks after Harry appeared to suggest his father Prince Charles, the Queen and the Duke of Edinburgh had failed as parents.
Speaking on the Armchair Expert podcast, the Duke said he wanted to "break the cycle" of "genetic pain and suffering" for the sake of his own children.
He said of Charles: "He's treated me the way he was treated, so how can I change that for my own kids?"
Prince Harry made new claims during his chat with Oprah
Harry, 36, picked up the theme again with Oprah, telling her in the series: "My father used to say to me when I was younger, he used to say to both William and I, 'Well it was like that for me so it's going to be like that for you.'" The Palace are yet to comment on the latest revelations.
