Zara and Mike Tindall have finally announced the name of their second child, nine days after she was born.
A spokesperson for the couple revealed today that the new arrival had been named Lena Elizabeth, believed to be a nod to Zara's grandmother the Queen.
Princess Anne's daughter and her rugby player husband, who already have 4-year-old daughter Mia Grace, welcomed a little girl on June 18.
The new arrival was born at Stroud Maternity Unit in Gloucestershire weighing 9 lbs 3 oz (4.2kg), the Palace said.
The youngster is believed to be the heaviest royal baby in recent years; the record was previously held by Zara's niece Savannah Phillips, who weighed 8lb 8oz (3.9kg) when she was born in 2010.
Zara and Mike Tindall announced this week that their 9-day-old daughter is called Lena Elizabeth.
Although the baby's second name is likely to be a touching tribute to her great-grandmother, what does her first moniker mean?
According to BabyCenter.com, Lena is a Greek word that means "light".
The new Tindall baby's name is pronounced lay-na, and not the other variation of lee-na.
According to a spokesperson for the couple, the choice didn't have a special meaning. They said: "The name is Lena Elizabeth. It was just a name they liked."
Lena is a popular name in Wales and Sweden, where it is both a male and female name.
Baby names expert SJ Ljungstrom, from ChannelMum.com, told MailOnline: "Zara is a royal with a modern twist and her choice for her new daughter perfectly reflects this.
"Just like for first daughter Mia Grace, Zara and husband Mike Tindall have chosen an contemporary moniker for the baby's first name and a heritage counterweight for the second name.
"Lena is a pretty and contemporary name, which is rocketing in popularity, up from 823rd to 138th in position in the last ONS figures.
"This is partly due to the popularity of millennial writer Lena Dunham and actress Lena Headey."
"Elizabeth is, of course, a homage to Zara's grandmother the Queen and a traditional royal name favoured for generations. It adds weight and substance to the more contemporary choice of Lena.
"Elizabeth is always in the top 100 chart for girls' names and although it has slipped from 26 to 38 in recent years, Zara's choice should spark a mini revival by reminding people how elegant and versatile it is.
"Zara has managed to please all camps at once - royalists, modern mums and her own family, making this a perfect baby name choice.
"There's some debate around the name origin and meaning. Some people claim it is of Greek heritage and means 'light and shine', which is so appropriate for a summer baby.
"It's also seen in Swedish, Finnish and even Hindi where it means 'generous and kind'.
"It's very popular in Hawaii where is it also spelled Lina and it recently topped the list as the most popuar name for girls in Poland in 2013, which may explain its rise in the UK too."
