Zara Phillips and Mike Tindall have named their baby daughter Mia Grace.
Former England international rugby star Tindall tweeted: "For everyone who has asked what our daughters name, it's Mia Grace Tindall."
Zara gave birth last week to the 7lbs 12oz girl, who is 16th in line to the throne and is the Queen's fourth great grandchild.
Tindall took to Twitter after the birth to describe his joy at becoming a father for the first time, saying it was "definitely the best day of my life".
Zara, a silver medal-winning Olympian, who is one of Britain's leading equestrian riders, gave birth to her first child at Gloucestershire Royal Hospital with her husband at her side.
