The Queen's granddaughter Zara Phillips and Mike Tindall got married in Edinburgh in 2011
The Queen's granddaughter Zara Phillips and rugby player Mike Tindall are expecting their first baby in the new year, Buckingham Palace has said.
The couple married at Canongate Kirk, in Edinburgh, in July 2011.
The birth will follow the arrival of the Duke and Duchess of Cambridge's baby, which is due this month, reports the BBC.
In a statement, Buckingham Palace said: "Mr and Mrs Mike Tindall are very pleased to announce that Zara Tindall is expecting a baby in the new year."
It said the couple's parents, the Princess Royal and Captain Mark Phillips, and Mr Phillip and Mrs Linda Tindall, and members of both families were "delighted".
"This baby will be the first child for Mike and Zara and the third grandchild for the Princess Royal."
Mike Tindall took to Twitter to express his gratitude to well-wishers. "Thanks for all the kind messages, we are very excited," he wrote.
The former England rugby player, who has broken his nose eight times, also joked: "I agree with you all that hopefully he/she won't have my nose".
Ms Phillips' brother Peter has two daughters, Savanna and Isla.
Prime Minister David Cameron's official spokesman described the announcement as "quite terrific news".
He told reporters: "The prime minister will send his very, very best wishes to the happy couple."
The new baby will become 16th in line to the throne and the fourth great grandchild to the Queen and the Duke of Edinburgh.
The others are Savannah and Isla, and the Duchess of Cambridge's expected baby.
Ms Phillips, 32, does not hold a royal title and is not an HRH. After her marriage, she decided to keep her maiden name.
Her children will be titled Miss or Master Tindall.
