Princess Anne's son Peter Phillips and his wife, Autumn, delayed the announcement of the happy news of their first pregnancy, who would be the Queen's first grandchild, until July 2010, when they joined the royal family for a cruise around the Scottish islands on the luxurious liner, Hebridean Princess.
The Queen was said to have been touched that they had chosen to keep the news a secret until they were all together as a familyeven though Autumn was already four months pregnant.
The condition suited the Canadian-born former management consultant, who looked both radiant and glamorous throughout her pregnancy.
Peter and Autumn had been living in Hong Kong, where Peter worked for the Royal Bank of Scotland, but returned to the UK permanently before the birth.
Savannah Phillips arrived just as 2010 drew to a close at Gloucestershire Royal Hospital, weighing 8lb 8oz.
Proud father Peter, the Queen’s eldest grandchild, was at Autumn’s side during the birth.
An official statement from the Palace said that the Queen and her family were "delighted" with the news, with Princess Anne also celebrating becoming a grandmother for the first time.
"Hopefully, we'll be blessed with at least one child," Autumn told HELLO! on the eve of her wedding. "When the time comes I don't want to have a child and hand it over to somebody else. I'd like to raise my own children."
