Speaking in the latest episode of The Good, The Bad & The Rugby, Tindall said: “It’s been a good week for me, had a little scan last week – third Tindall on its way.”
He went on to say that he would like the child to be a boy this time. The couple already have two daughters, six-year-old Mia and two-year-old Lena.
“I’d like a boy this time, I’ve got two girls, I would like a boy,” he said, adding: “I’ll love it whether a boy or a girl – but please be a boy.”
The sports star also joked about a potential name for the baby, suggesting the couple could take inspiration from the coronavirus pandemic.
“We’re not sure what to do Covi or Covina – I don’t know where to go with names,” he jested.
A Buckingham Palace spokesperson said the Queen and Duke of Edinburgh are “delighted” by their granddaughter’s pregnancy. However, during the podcast Mike revealed that their eldest child has still not been told the news.
“We haven’t told Mia yet because we knew she would tell everyone at school, now that we’ve gone through the scan, yes (of) course we’ll tell her,” he explained.
“She’ll be happy about it, she’s been requesting another sister or brother, so we’ve hopefully fulfilled that role for her. She just wants something different now, Lena’s growing up she’s two-and-a-half now, she wants something younger to play with and dress up.”
Mike also opened up about how the couple are handling the pregnancy following two previous miscarriages.
“Z is very good, always careful because of things that have happened in the past, and really looking forward to it,” he said.
Almost three years after the birth of their first daughter, the couple announced their second pregnancy in November 2016. But, just a month later on Christmas Eve, Zara and Mike shared the news that they had gone through a miscarriage.
"Very sadly, Zara and Mike Tindall have lost their baby. At this difficult time, we ask that everyone respects their privacy," a spokesperson for the couple said at the time.
The royal said it happened “really early on” in another pregnancy, which was never shared with the public.
“You need to go through a period where you don’t talk about it because it’s too raw but, as with everything, time’s a great healer,” she said.
