The blonde beauty posed up a storm with her fellow co-stars Lydia Bright, Ferne McCann and Georgia Kousoulou as they prepared for a day of press ahead of the start of series 13 of the reality show.
Billie only gave birth to daughter Nelly in July, but she's already taken the opportunity to show off her post-baby figure by sporting a pair of high-waisted forest green trousers.
Opting for a smart getup for the occasion, the yummy mummy added a white blouse which she tucked into her trousers, styling her blonde hair extensions in beachy, mermaid-esque waves while flaunting her sparkling engagement ring (courtesy of fiancé Greg Shepherd!).
The starlet threw her arm around Lydia, who looked equally as gorge while flaunting her pins in a bright electric blue drop-hem dress teamed with a statement layered silver necklace.
Ferne oozed effortless chic in monochrome by sporting a leather skirt and a laid-back white tee, while Georgia opted for girly glamour in a floral jumpsuit paired with red lipstick and swept-back tresses.
Lydia, Ferne and Georgia have all recently jetted back from Ibiza where they filmed two special episodes of the reality show, which will kick off the new series on 8 October.
Meanwhile, Billie has been enjoying time back home in Essex with her tiny tot, and has also confirmed that Nelly is set to become TOWIE's youngest star as she'll be appearing in future episodes of the show.
