The TOWIE star shared a selfie from her now-familiar white bedroom via Instagram on Wednesday (26 March), showing herself trying out a new arrival to the boutique.
"Love this cute dress," she told followers, with Minnies adding it's available to buy online now.
Perfect for a hot summer's day, we think, maybe not so much right now when we're still bundling up in coats and scarves every morning!
The cut of the dress hid Billie's growing baby bump. In fact, we wouldn't have suspected one was there if we hadn't known she is pregnant.
Bubbly Billie became the first TOWIE star to announce a pregnancy when she revealed in January that she and partner Greg Shepherd are expecting.
Then, shortly afterwards, she announced more happy news: long-time boyfriend Greg had proposed while they were in the Maldives!
Essex star Billie has already revealed she is expecting a little girl, breaking the news to friends and family at a party shown on an episode of TOWIE earlier this year. Viewers saw Billie and Greg reveal the baby's sex by cutting into a cake which had pink sponge filling.
