Last Thursday, Reveal broke the news that Billie had given birth to her daughter and it's clear Sam has wasted no time getting to know her niece.
The pair already share a special bond, as Sam was present during Billie's labour, and she is obviously besotted with the latest edition to the family.
Last night (15 July), Sam took a selfie as she gave her baby niece - who is yet to be named - a cuddle at home. Sharing the snap on Instagram, she said: "Cuddles are the best with my baby niece, I love u xxx."
Although the photo doesn't show either of their faces, it is still a very touching image nonetheless.
Yummy mummy Billie was pictured out and about yesterday and the smile on her face said everything about how she's feeling right now.
Dressed in a jumpsuit, which she wore during her pregnancy, Billie proudly showed off her post-baby figure as she and fiancé Greg Shepherd dashed to the shops to pick up some essentials for their little girl.
Referencing her daughter on Twitter during the afternoon, Billie simply said: "Mummy's perfect little angel ... #love."
