The Duchess of Cambridge has said she "can't wait" to meet her new niece, Lilibet Diana.
Catherine said she wished the Duke and Duchess of Sussex's newborn daughter "all the very best", at a G7 summit of world leaders in Cornwall.
"We haven't met her yet," she told reporters. "I hope that will be soon."
The duchess was quizzed about her new niece after meeting US First Lady Jill Biden for the first time on a joint visit to a Cornish school.

She was born in a Californian hospital on 4 June, and named in honour of Prince Harry's mother, Diana, Princess of Wales, and grandmother, the Queen.
Catherine's daughter Charlotte is also named after the Queen and Princess Diana, having the middle names Elizabeth and Diana.
Asked by a journalist whether she had any wishes for Lilibet, Catherine said: "I wish her all the very best. I can't wait to meet her."
The duchess was also asked whether she had spoken with Meghan via video-calling app FaceTime. "No I haven't," she replied.
The questions came at the end of Catherine and Dr Biden's visit to a primary school, where they had been discussing children's early years development.

The duchess and first lady toured a classroom meeting some younger children at Connor Downs Academy in Hayle, which teaches four to 11-year-olds.
Mrs Biden, 70, has spent decades working as a teacher, and has a doctorate of education from the University of Delaware.
She was a professor of English while her husband served as vice-president, and has previously said: "Teaching is not what I do. It's who I am."
She and the duchess also brought carrots which were fed by pupils to the school's pet rabbits.
