Queen Elizabeth's granddaughter Zara Tindall and her husband, former rugby player Mike Tindall, are celebrating the birth of their third child, who was born at home after the couple was unable to get to a hospital in time.

Tindall, the former England rugby union captain, broke the news during a rugby podcast show, saying the couple's third child Lucas Philip Tindall was born on Sunday (March 21) on the bathroom floor at the family's home and weighed 3.8kg.

His middle name is in honor of both Mike Tindall's father as well as Zara's grandfather, Prince Philip.

He is 22nd in line to the throne, but won’t take the His Royal Highness title.

Tindall, 42, revealed that the speed of the arrival of the latest royal baby — he is the Queen's 10th great-grandchild — caught the couple off guard and that he had to rush to get a mat for his 39-year-old wife, who, like her mother, Princess Anne, enjoyed a successful equestrian career.

“So yeah, it was running to the gym, get a mat, get into the bathroom, get the mat on the floor, towels down, brace, brace, brace," he said on The Good, The Bad & The Rugby podcast.

 

The newest addition to the Tindall family is a younger brother to 7-year-old Mia and 2-year-old Lena, who weren't at home at the time of the birth.

Tindall said his wife’s friend Dolly, who was also at the previous two births, was present.

“She was there and recognised that we wouldn’t have got to [the] hospital in time," he said.

"Fortunately, the midwife who was going to meet us at the hospital wasn’t that far away so she drove up just as we had assumed the [position] and the second midwife arrived just after the head had arrived.”

Tindall joked that now may be the right time for him to have a vasectomy.

“I literally was like ‘Yep, snip, snip, snip.’ I’ve got a boy. I’m out. I’m out of here," he said.

“The best thing about being at home, the best thing was, as soon he’s wrapped up, he’s skin-on-skin, straight downstairs. TV room. Golf on. This is what we’re doing.”
