The Essex reality star told The Mirror's TV Life that she has no plans to follow in sister Sam's footsteps and quit the ITVBe show just yet.
Billie, 26, said: "I am [staying] for now. I don't film as much as I used to because of my daughter and the filming schedule. They're really good and will try to do it around me. I'm definitely committed to the show for now."
The Minnies Boutique co-owner, who is engaged to businessman Greg Shepherd, gave birth to daughter Nelly in July last year. Nelly has popped up in the show from time to time.
Sam left TOWIE two years ago. At the time, she wanted to focus on her relationship with then-boyfriend Joey Essex, and her health, after being diagnosed with Crohn's Disease while in the Celebrity Big Brother house.
She later split with Joey and began dating Paul Knightley. They welcomed their first child, son Paul, in December last year.
The Mummy Diaries will air across six episodes this year.
