Billi, who is pregnant with her first child, was pictured with Lauren and a group of girls at the glitzy event in Loughton.
The party was held to celebrate the opening of new salon Beauty Box and both ladies walked away with goodie bags packed with treats. Well jel!
In the group photo, Billi can be seen covering her growing baby bump with a loose-fitting floral top. She teamed it with a smart cream blazer and simple black trousers.
Lauren, meanwhile, who didn't star in TOWIE at the same time as Billi, was also rocking black skinnies but opted for a smart/ casual tee.
Looking good, girls!
Yoga instructor Billi announced her pregnancy on Christmas Day after posing alongside her footballer fiancé, Andy Carroll, in a sweet and festive snap.
Since then, Billi has kept fans updated with lots of pictures of her growing baby bump and is thoroughly looking forward to becoming a mum this summer.
In a recent interview with Reveal, Billi revealed she has been stocking up on baby essentials ahead of the birth and already has THREE prams!
