The TOWIE babe took a glamorous selfie with the caption: ‘Out for dinner with the girls...#babybump.’
She also tweeted: ‘Ready for our girlie dinner .. Thank you @HairHutEssex for my lovely blow dry...’
It truly is a ladies night for the TOWIE babes as Billie revealed on the show that her and fiancé Greg Shepherd are expecting a baby girl.
'I'm so excited. I had a feeling I was going to be having a girl,’ Billie recently told a UK magazine.
The pregnancy was announced shortly before Greg proposed to Billie during a romantic holiday in the Maldives.
Billie said: ‘I had no idea he was going to propose! Even when we got there and I saw two chairs with a bottle of champagne, I didn't suspect a thing.’

Billie was joined by sister Sam, who is looking much healthier following her Crohns disease diagnosis.
Sam posted her own selfie with the caption: ‘Out tonight with my girls..@riverisland leather skirt Giuseppe shoes and @thisisalovesong top.’
We wonder how long Billie will be fitting into those LBDs now!
