Zara Tindall, the Queen's granddaughter, and her husband Mike Tindall are expecting their second child.
The lovely baby news have been revealed by a spokesperson for the couple, who said that the entire family is 'very pleased'.
'The Queen and members of the royal family were very pleased to hear this news', a Buckingham Palace spokesperson said.
Zara's second child is believed to be due in the summer, according to Hello! magazine, so their new baby will only be a few months younger than its royal cousin also due to be born in 2018 - Kate and Wills' third child.
It also means that Zara is very likely to be pregnant when she attends her cousin's wedding in May - Prince Harry and Meghan Markle's big day.
The couple are already parents to Mia, who's turning four this month and famously held the Queen's handbag in a Royal portrait of monarch that was taken for her birthday.

Speaking about the adorable moment, her dad Mike said: 'It just happened at the right time. She was being a bit naughty. The queen got it quite right when she told her: "Just hold the handbag now".
'And she did that. It ended up being a great photo for her.'
The Olympic equestrian and her ex-England rubgy player husband Mike tied the knot in July 2011 at Canongate Kirk in Edinburgh, only a few months after announcing their engagement in December 2010.
Two years later they revealed they were expecting their first child, in July 2013, and they welcomed Mia in January the following year.
The joyous news come more than a year after the couple revealed that they lost a baby, in December 2016.
'Very sadly, Zara and Mike Tindall have lost their baby. At this difficult time, we ask that everyone respects their privacy', the couple announced in a statement at the time.
Speaking about their loss, Mike told Sunday Times last year: 'One thing you do learn is how many other people have to go through the same thing.
'The saving grace for us has been Mia, our daughter, who is now three. However down we feel she will come running up in our faces. When I was playing [rugby] I hardly saw her; now we can see her grow up. I can take her swimming and I can take her to Ninja Tots. You'll never be able to see her there because she disappears in a puff of smoke.'
