The newest member of little Prince George
's family has a name.
Zara and Mike Tindall
have decided their daughter
will be Mia Grace Tindall, the rugby star announced on Twitter
Mia, who will be 16th in line to the British throne, was born Jan. 17
at the Gloucestershire Royal Hospital. She weighed 7 lbs., 12 oz.
Zara, 32, who is a godmother to Prince George, is expected to release the first photo of the littlest royal in the coming days.
The name Mia Grace will surely delight bookmakers, who accept bets on royal baby names.
One firm, Ladbrokes, had stopped taking wagers on the name Poppy after a run of bets in the Gloucestershire area. But the distinctly un-royal name Mia (who won't have an official royal title) didn't appear on the Ladbrokes list – meaning that very few people, if any, bet on it.
Talk about great odds.
