Zara Tindall has given birth to a baby boy, her husband Mike Tindall has announced.
The former England rugby star revealed the news in his podcast, The Good, The Bad and The Rugby.
A spokeswoman for the couple said: "Zara and Mike Tindall are happy to announce the birth of their third child, Lucas Philip Tindall."
The baby, who is a new great-grandson to the Queen, was born on Sunday 21 March, weighing 8lbs 4oz.
The Tindalls, who live on the royal Gatcombe estate in Gloucestershire, already have two children - Mia, seven, and Lena, two - and have been married since 2011.
Lucas is the Queen and the Duke of Edinburgh's 10th great-grandchild, but is only 22nd in line to the throne.
Mike Tindall had joked about wanting a boy this time around.
The baby's birth comes just a few weeks after Zara's cousin Princess Eugenie had her son August on 9 February.
