Billi is a trained yoga instructor and left The Only Way Is Essex last year to open a Bikram yoga studio - and by all accounts, its doing really well!
Yesterday, Billi proved just how flexible she is by posing for a picture while arching right back and holding her ankles.
After posting the snap on Twitter, Billi told her followers: "Morning! Yoga Time @Bikramyogaessex #bendy #bikramyoga #backbends #peace #love."
Ex reality star Billi announced she was quitting TOWIE last May.
A month later, her former TOWIE co-stars, including Cara Kilby, Danni Park-Dempsey and Frankie Essex, joined Billi at the official opening of Bikram Yoga Essex in Loughton.
Speaking about her love of yoga, Billi admits it was her father who first introduced her to it.
"My dad, who practises five times a week and started yoga a year before me, advised me to try it with him over at Canary Wharf," Billi says.
"After that first session, I wasn't sure. I was one of those people that would say, 'I don't like this'. Everyone said, 'Come back and give it another go', which I now preach.
"Now I'm an addict and love everything about it. I wished to teach it, so I studied and now have my own studio."
