The Essex reality star took to Instagram to flaunt her "little bump" in a cute 'n' cosy knitted dress after sharing the exciting news a son is on the way.
Oh, and if you fancy stealing Billie's style, this little number is from her InTheStyle range, available in grey and cream for £24.99.
Clearly Billie is loving her knitted dresses this winter, as she also shared another photo of her in a cream roll neck jumper dress.
"Winter knits for keeping me and baby bump warm!" she declared. This frock is also an InTheStyle number (of course!) available now for £39.99.
Billie announced in OK magazine this week that she and fiancé Greg Shepherd will welcome their first son in the New Year. They're already parents to daughter Nelly, two.
The 26-year-old has admitted the baby's gender was a surprise as she'd been convinced a second girl was on the cards.
"We're in complete shock. Greg and I always thought we'd just have girls and everyone around us put that in our heads, too," she said.
"We couldn't stop laughing during the scan, I said to the sonographer: 'No! Are you sure? Can you check again?' She checked a few times so it's definitely a boy. We can't stop smiling."
Billie's sister Sam Faiers also has a little boy, baby Paul, who was born in December last year.
