ZARA and Mike Tindall have named their baby daughter Lena Elizabeth, a spokeswoman for the couple said.
The name is thought to be a touching tribute to Zara's grandmother Queen Elizabeth.
Buckingham Palace said in a statement after the tot's birth last week: "The Queen, The Duke of Edinburgh, The Princess Royal, Captain Mark Phillips and Mike’s parents, Mr Philip 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 second child for Zara and Mike, the fourth grandchild for The Princess Royal and the seventh great-grandchild for The Queen and The Duke of Edinburgh."
The child is now 18th in line for the throne.
Zara, 36, and Mike, 39, are also mum and dad to daughter Mia Grace Tindall, three. Horse-riding Olympian Zara’s girls will not have titles.
A spokesman for Queen’s granddaughter Zara, 37, said the couple were “very happy” after the birth on Monday 18 June.
The sporting couple have been married for nearly eight years and met during England's Rugby World Cup-winning campaign in Australia in 2003.
They were introduced to each other in a bar in Sydney by Zara’s cousin Prince Harry.
In 2010 they announced their engagement and married on July 30 2011. Their first child, daughter Mia, was born in January 2014.
The couple were left heartbroken on Christmas Eve 2016 when they lost a child, just weeks after they had announced the pregnancy.
