The 35-year-old reality star – daughter of former footballer Paul 'Gazza' Gascoigne – is expecting her first child, due in February 2023, with partner Aaron Wright after one year of dating.
Bianca shared on her Instagram account: "We’re having a baby... Coming February 2023."
The bed is covered in baby toys and junk food and Bianca is smiling while eating a pizza, while Wright is holding a pregnancy test and parenting manual and looking shocked.
Knocked Up is a romantic comedy about a couple who unintentionally fall pregnant after a drunken one night stand, but then decide to have the baby together and eventually fall in love.
Bianca and Wright have been dating for a year, celebrating their anniversary in Paris on 7 August 2022.
But they have been friends for 14 years, having met at a party at the Dubai races in 2008.
Bianca told Closer magazine earlier this year: "We'll get married. He's husband material, and I can see us getting engaged soon."
She previously told the magazine in June 2021 that she had frozen her eggs as she new she wanted to have a family and didn't want to leave it too late.
The former Celebrity Big Brother contestant said: "I’m 35 in October and I’m at the age where women start to worry about their biological clock.
"I definitely see settling down and having kids as the next stage in my life, but seeing as I’m single now it makes sense to do this as a kind of insurance."
She made it to the final of Celebrity Big Brother in 2017 and was runner-up in the Italian version of Dancing With The Stars in 2021.
