Proud uncle Prince Harry reacts to Prince William and Kate's baby news

By Gemma Strong

Prince Harry has shared his delight following the news that he is set to become an uncle for the third time. Hours after the announcement that William and Kate are expecting another baby, Harry made an appearance in Manchester to meet with victims of the Ariana Grande concert bombing. He was asked by reporters how he felt about the pregnancy news. "Fantastic, great," he replied, giving a thumbs up. "Very, very happy for them." He also revealed that Kate was doing "ok" as she battles Hyperemesis Gravidarum, a severe form of acute morning sickness that has afflicted all of her pregnancies. "I haven't see her for a while, but I think she's ok," he said.

The news that Kate is pregnant again means that Prince Harry will move down to sixth in line to the throne. Kensington Palace announced on Monday that the royal couple are expecting a sibling for Prince George, four, and three-year-old Princess Charlotte: "Their Royal Highnesses The Duke and Duchess of Cambridge are very pleased to announce that The Duchess of Cambridge is expecting their third child. The Queen and members of both families are delighted with the news," the official statement read.
