English rugby star Mike Tindall’s 78,000 Twitter followers were the first to know what he and wife Zara Phillips have named their royal baby.

Tindall tweeted around 9 a.m. to announce that they have named their daughter Mia Grace Tindall.

Phillips, the daughter of Princess Anne, gave birth to Mia Grace at Gloucestershire Royal Hospital on January 17. The newest addition to the royal family is 16th in line to the British throne and the Queen’s fourth great-grandchild.
