This is the couple's second child.
Boris Johnson and his wife Carrie have confirmed the name of their rainbow baby.
The couple has chosen quite the sweet moniker for their baby girl.
Carrie revealed their baby girl is called Romy Iris Charlotte Johnson.
The mum-of-two posted a photo of their son Wilfred gazing at his little sister as she slept.
"Welcome to the world darling Romy. Born on December 9 at 9.02 am."
"Romy Iris Charlotte Johnson. Romy after my aunt, Romsemary. Iris from the Greek, meaning rainbow. Charlotte after Boris' late mum who we miss so much."
Carrie confirmed she suffered a miscarriage before welcoming her daughter.
"Hoping for our rainbow baby this Christmas. At the beginning of the year, I had a miscarriage which left me heartbroken," she revealed.
"I feel incredibly blessed to be pregnant again but I've also felt like a bag of nerves.
"Fertility issues can be really hard for many people, particularly when on platforms like Instagram it can look like everything is only ever going well.
The mum said their son Wilfred is settling into his role as big brother.
"Wilf has been stroking Romy's hair, giving big kisses, and playing with his matchbox cars right next to her crib, just in case she feels like joining too."
Carrie also praised the healthcare workers in her sweet post.
"Thank you so much to the amazing maternity staff at UCLH for looking after us so well. We are so, so grateful," she gushed.
Baby Romy is Boris and Carrie's second child together.
Their first baby Wilfred was born in April of last year, only a month after Johnson's battle with Covid-19.
