The boutique owner and mum-of-one was smokin' hot in a risqué halterneck dress while attending an International Women's Day party thrown by co-star Gemma Collins on Wednesday (4 March).
How AMAZING does she look?!
Billie teamed her slinky frock with metallic strappy sandals, a statement pair of earrings, flawless make-up and a chic low ponytail.
We've been loving watching Billie on the new series of TOWIE as she's been treating us to glimpses of her baby Nelly!
Little Nelly has appeared in the new season twice – one while Billie was having lunch with Lydia and Ferne, and then last night while she was chatting with Gemma Collins. Aww!
Billie's been nominated for 'Mum of the Year' at the IceLolly.com awards and recently said just been recognised alongside the likes of fellow nominee Katie Price had been a big honour.
"Such amazing names have won in the past like Katie Price and with this being my first year as a mother it is really special that the public have voted enough for me to be shortlisted.
"I have told Nelly that her mummy is now in a competition to win the Celebrity Mum Of The Year Award. I'm sure if she was old enough she would vote for me as well. At least I'm hoping she would!"
