Zara Phillips and Mike Tindall have named their baby girl Mia Grace, six days after she was born.
The very modern name was announced in a very modern way - by dad Mike on Twitter, just after 1pm.
He wrote: "For everyone who has asked what our daughters name is, it's Mia Grace Tindall."
Her name defies bookies' expectations that she would be given a more 'traditional' moniker, such as Elizabeth or Anne.
According to the Office for National Statistics, Mia was the seventh most popular name for a girl in 2013, and Grace was 14th.
Other famous Mias are, of course, actress Mia Farrow and Mia Honey Threapleton, the 13-year-old daughter of Kate Winslet and her first husband Jim.
Mia Grace Tindall was born on January 17, weighing 7lb 12 oz, at the Gloucestershire Royal Hospital. She is the Queen's fourth great-grandchild and is 16th in line to the throne. A statement from Buckingham Palace at the time said: "The Queen, The Duke of Edinburgh, The Princess Royal, Captain Mark Phillips and Mike's parents, Mr Phillip and Mrs Linda Tindall, have been informed and are delighted with the news. The baby's name will be confirmed in due course.
"This baby is the first child for Zara and Mike, the third grandchild for The Princess Royal and the fourth great-grandchild for The Queen and The Duke of Edinburgh, and is 16th line to the Throne."
Mia Grace is Princess Anne's third grandchild.
Zara's brother Peter and his wife Autumn have two daughters: Savannah Anne Kathleen, who turned three in December, and Isla Elizabeth, who will be two in March.
