The TOWIE favourite is currently enjoying a holiday in sunny Dubai with fiancé Greg Shepherd, sister Sam Faiers and their mum, and she took a break from sunbathing to share a couple of photos with fans via Instagram.
In the snaps, taken from what appears to be their glam hotel room, the blonde star proudly holds her bump while posing in a lime green halterneck bikini.
"Me and bump ready for the beach," she told fans.
Billie's fans were quick to lavish praise on the pregnant star, with comments on Instagram ranging from "stunning" to "you look incredible" to "beautiful" – and we wouldn't disagree!
She was looking very bronzed in the snaps and recently revealed to us her choice of fake tan.
"I've never been a massive fan of spray tans anyway but lately I've been loving Garnier Summer Body. It's a gradual moisturiser that I apply once a week to get a subtle sun-kissed glow," she said.
The bubbly star is enjoying some relaxation following the end of filming on the eleventh series of TOWIE, which aired its season finale last week.
It was an eventful series for Billie who not only announced her pregnancy - and that she's expecting a baby girl - but also revealed her engagement to long-time beau Greg Shepherd, who made his first TOWIE appearance in February.
Greg popped the question while the couple were holidaying in The Maldives earlier this year.
