"My favourite princess is Kate Middleton," she said before getting confused over whether Kate was actually a princess at all. "But she's a duchess. She's a princess too, right? I'll go with Kate Middleton."
When questioned further by her six-year-old interrogator Anne admitted she thinks that the Duchess of Cambridge, who is currently on a three-week tour of New Zealand and Australia with Prince William and eight-month-old Prince George, "is lovely".
Speaking on Good Morning America, Anne said: "I think she's lovely. She makes me very happy and that royal wedding just could not be beat."
But Anne isn't the only famous face who's a fan of Kate. Reality television star Kourtney Kardashian recently revealed she is also a duchess devotee.
"'I love how she mixes designer pieces with price-friendly fashion that is accessible for women worldwide," she told Hello! in February.
