The 33-year-old model - who has Golden, three, with Nick - has taken to social media to announce the arrival of Powerful Queen Cannon.

Alongside some family photos, Brittany wrote on Instagram: "The best gift ever [heart emoji] we have been surprised with... A GIRL!!!!! [crown emoji] Powerful Queen Cannon [crown emoji] came this week perfect timing for Christmas. So much more to share. All I can say is that Nick was my rock through the most intense yet empowering natural water birth. It was nothing but POWERFUL [heart emojis] Merry Christmas!!!! THANK YOU GOD (sic)"

Nick, 40, started dating Brittany in 2014, but their romance has endured plenty of ups and downs over the years.

In 2016, for example, the couple were separated when it was announced they were expecting their first child together.

The TV star - who has nine-year-old twins Moroccan and Monroe with ex-wife Mariah Carey - previously admitted he was open to the idea of having more children.

He shared: "I'm not against it. I talk about that all the time. I love children. Everybody knows that.

"Whether it's having more of my own, or adopting, whatever, I love that process. Kids kind of bring that vibrant side [out] of me so whenever I can be a part of that process I'm with it."

Nick also described fatherhood as what he was "put on this Earth to do".

The comedy star - who was married to Mariah between 2008 and 2016 - said: "We're here to be fruitful and multiply. That's what our beings are made for, so we can raise our offspring up so they can have offspring, and [have] generations after generations."
