"The Prince, of course, hasn't seen his grandson Archie for a bit of time and so it was very, very, very special to have some time with him. He hadn't met Lili, his granddaughter, and so to meet her was very emotional, a very, very wonderful thing."
Lili also met her namesake, her great-grandmother the Queen, for the first time and enjoyed her first birthday party at Frogmore Cottage, Meghan and Harry's UK base.
