Prince Louis isn't the only royal baby in London. Prince William and Kate Middleton's son also has newborn second cousin. Zara and Mike Tindall announced the birth of their daughter earlier this week. The 9-pound, 3-ounce baby was born on June 18, 2018— a year and a half after Zara revealed she had suffered a miscarriage.

While the palace has not yet announced the child's name, the new mom of two is undoubtedly taking her time to get to know the littlest member of the royal family. Here's what you need to know about Zara — and first things first, she's not named after the clothing store.

She's the Queen's granddaughter and 17th in line to the throne.

Princess Anne and Captain Mark Phillips welcomed Zara Anne Elizabeth Phillips on May 15, 1981 at the Lindo Wing of St. Mary's Hospital — where Princess Diana and the Duchess of Cambridge would later give birth. Her middle names paid homage to her mother and grandmother respectively, but "Zara" — a name with French origins meaning light — reportedly came as a suggestion from her uncle Prince Charles.

The newborn baby was the Queen's second grandchild after older brother Peter Phillips. Zara initially attended school in England before moving to Gordonstoun — a Scottish boarding school — that also counts Prince Philip and Prince Charles amongst its alumni. She then studied as a physiotherapist at the University of Exeter.

She doesn't have a royal title.

Per the Letters Patent issued by King George V in 1917, only male-line grandchildren of the monarch receive the title prince or princess. The Queen offered to make an amendment for her only daughter, but Princess Anne declined.

She wanted to give her children a more "normal" childhood, and it looks like the Princess Royal made the right call. "I’m very lucky that both my parents decided to not use the title and we grew up and did all the things that gave us the opportunity to do,” Zara told The Times in 2012.

She's won an Olympic medal.

Like her mom and dad, Zara established herself as an accomplished equestrian. She qualified to compete at both the 2004 and 2008 Summer Olympics, but her horse suffered injuries both years during training.

In 2012, she finally received her shot at Olympic glory in her hometown at the London Games. She won a silver in the team event and in a fitting turn of events, her mother presented the medal.

Zara's athletic success and celebrity status has enabled her to earn living sans an allowance from the palace. In 2003, she became the first member of the royal family to sign a sponsorship deal by repping the betting site Cantor Index. Zara also launched her own clothing line with the British brand Musto called ZP176.

Her husband is Mike Tindall.

Zara had previously dated jockey Richard Johnson for five years, but in 2003 she met English rugby player Mike Tindall. As the captain of the national team, Mike had just won the 2003 World Cup in Australia — not too shabby. They dated for several years before announcing their engagement on December 21, 2010.

Per the rules at the time, the Queen technically had to approve the match but she gave the official go-ahead. The couple married on July 30, 2011 in Scotland, with Zara wearing an off-the-rack Stewart Parvin wedding dress and her mother's Meander Tiara.

While Zara was still competing as of last fall, Mike has since retired from rugby.

They have two kids.

On January 17, 2014, Zara gave birth to her daughter Mia Grace Tindall. The rambunctious 4-year-old now rubs elbows with Prince George and Princess Charlotte.

In December 2016, just weeks after publicizing her second pregnancy, the couple announced that Zara had suffered a miscarriage. Mike later shared how their bubbly little girl had helped them through that difficult time.

"However down we feel she will come running up in our faces,” Mike told The Sunday Times in May 2017. "When I was playing 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."

The latest happy news makes Mia officially a big sister. The safe delivery of Zara and Mike's second child on June 18 "delighted" the couple's parents as well the Queen and Prince Philip, per an announcement from the palace. The yet-unnamed infant is the monarch's seventh great-grandchild.
