In May, Billi revealed she was leaving TOWIE to open her own studio - and it seems all her hard work has paid off.
Looking glam in a floaty black dress, Billi was all smiles at the official launch event for Bikram Yoga Essex, held in Loughton, as she mingled with TOWIE stars both past and present.
Billi's best friend, Cara Kilbey, was on hand to offer her support in a gorgeous orange gown, while Frankie Essex was spotted in a pretty pink skater skirt teamed with a simple white vest.
Fellow former star Danni Park-Dempsey also turned heads in a lime green number with Chanel bag, while Chloe Sims rocked a racy black lace long-sleeved top with white pencil skirt.
Fresh from his split with Sam Faiers, Joey Essex joined in the fun in a yellow jacket, cargo pants and a snazzy baseball cap.
Following the party, Billi took to Twitter to thank her pals for attending: "What an amazing night, lucky to have a beautiful studio such great friend and family! Thank you everyone for making it a night to remember."
This morning, she added: "Today I'm feeling tired!" We're not surprised, it looked like a great party!
