The TOWIE star showcased her growing bump in a tight dress on Sunday (27 April), sharing a selfie with fans in front of her now very familiar bedroom mirror.
Billie smartened up her navy and white frock with a chic beige trench coat and luscious Chanel handbag. Lucky girl.
As always, the starlet's fans were quick to compliment her in droves. "Cutest bump ever, Billie you're glowing!" wrote one. A second follower even suggested Billie had put her in the mood for another child!
"Too gorgeous for her own good," concluded another.
Blonde Billie announced her pregnancy in January, and will be the first TOWIE lady to welcome a baby since the show started. (Co-star Chloe Sims is a mum to daughter Madison, born before TOWIE began to air.)
Since announcing her happy baby news, boutique owner Billie has been looking rather fabulous whether she's glammed up for a night out or dressed down in a comfy jumper, like she was on Saturday. (Love the neon orange!)
The baby's dad is her fiancé Greg Shepherd, who popped the question earlier this year while they were holidaying together in The Maldives.
Billie's pregnancy and engagement were briefly touched on during episodes of the eleventh series of TOWIE, which concluded earlier this month, but we're hoping to hear lots more about her life as a yummy mummy when the show returns for its twelfth and thirteenth seasons later this year.
