TOWIE's Billie took the adorable snap while Nelly sat on the floor in her beautifully decorated nursery at home in Essex.
In the picture, six-month-old Nelly has her head turned to the side and Billie has joked that she looks like a baby meerkat.
Sharing the photo on Instagram, Billie commented: "My little meerkat today ... Haha ...."
Reality star Billie and her fiancé Greg welcomed Nelly into the world in July and it's fair to say their little girl is growing up fast. In fact, she's practically talking already!
In a short Instagram video (below), Nelly can be seen jumping around in her baby bouncer before mouthing the word "bye" back at her mummy. Cute or what?!
Nelly is definitely already living the high life. Not only has she enjoyed yacht trips and beach walks in Dubai and shopping expeditions to exclusive department stores, the tot is about to experience her first spa day.
Billie has planned the girls' day with sister Sam and her former Celebrity Big Brother co-star Luisa Zissman.
Earlier today, Luisa posted a picture of a pink rubber ring on Twitter, telling the Faiers': "Look what's arrived @BillieFaiers, now Nelly will be floating around like a princess when you & @SamanthaFaiers come!"
What a life - and she's not even one!
