The TOWIE star and fiancé Greg Shepherd welcomed their first child together, Nelly Samantha, in July 2014 and it's clear Billie is LOVING being a mother.
Today, she shared a sweet image of herself cradling Nelly.
She told fans: "Cannot believe my beautiful Nelly is exactly 6 months old today ... I love her more then anything in the world and becoming a mummy to her has been the best experience of my life."
One fan replied: "What a perfect and lovely mum you have become, you have done a wonderful job and always look stunning."
Last month, reality star Billie admitted to Reveal she couldn't believe how fast time was flying since she'd given birth.
Billie told us that Nelly was now crawling, describing it as the "next stage".
"Up until now she has been a breeze, but now I'm like 'oh god, this is where it starts'," she said. "I'm excited. Although, soon I'm going to have to make everything safe around the house. I'm going to have to be getting a playpen, stair gates, plug socket covers... the lot!"
