On her Instagram stories, the former The Only Way Is Essex star shared an adorable picture of her little girl's foot.
Sam Faiers' manicured hand held the tot's tiny foot up for the camera, as she captioned it: 'Little tiny foot", alongside a purple love heart.
Sharing a heartwarming snap of her new family of four, Sam wrote: "Welcome to the world our beautiful baby girl."
In the black-and-white picture, the Mummy Diaries star can be seen lying in her hospital bed cradling her baby girl.
As her two-year-old son Paul kisses his mum on the nose, her boyfriend Paul Knightley sweetly gazes over his tiny new addition.
Sam announced the happy news of her newborn’s arrival in a statement, with her representative telling OK! Online: "Samantha and Paul are delighted to welcome a baby girl into the world, both mother and baby are doing well."
Sam and Paul, who decided not to find out the baby's sex, are already parents to son Paul Tony, who turns two in December.
Their latest arrival will be documented on the third series of her ITVBe show The Mummy Diaries.
The 26 year old recently confirmed she was filming another series of the fly on the wall look at her life with her partner and son.
Showing off her growing bump, she told her 1.9million Instagram followers: "Shooting for #TheMummyDiaries #Series3 today."
