The blonde boutique owner uploaded another snap to Instagram on Friday morning (31 January) showing herself wearing a red halterneck bikini and happily posing by the ocean.
With a view like that we'd have a smile like Billie's as well!
And, as if we didn't know it from her beaming face and other gorgeous holiday photos, Billie added the caption: "I love the Maldives!!! Hahahah xxx."
Billie, 24, looked a-mazing in her slinky bikini, with barely any hint of baby bump visible.
Only Way Is Essex star Billie confirmed in January that she and long-time boyfriend Greg Shepherd are expecting their first child together this summer.
Billie revealed the happy news via Twitter on 7 January, writing: "I am so happy to tell you all, that Greg and I are expecting our first baby! We are so excited!! Thank you for all of your kind messages."
Lucky Billie was whisked off on a birthday break to Paris by boyfriend Greg shortly after her announcement, and now the happy couple are holidaying in the Maldives.
She's the first TOWIE star to become pregnant. Co-star Dan Osborne was the first to welcome a child when his ex-girlfriend gave birth to son Teddy in December 2013. Ex-castmate Georgina Dorsett is also a mum, having daughter Nevaeh last year.
Billie's castmates have all sent their congratulations to her via Twitter, including younger sister Sam, who was only able to tweet her excitement yesterday as she's been cooper up in the Big Brother house.
"I can finally scream it from the rooftops. I'm so happy & excited to becoming an auntie. Love u so much @BillieFaiers & @Gregshepherd," she tweeted.
