Former TOWIE star Sam turned 25 today (31 December) and is marking the special occasion with boyfriend Paul Knightley and their little bundle.
Although they are yet to reveal the tot's name, Sam revealed yesterday that she had given birth to their son on Tuesday, adding that he is "beautiful".
She said: "Welcome to the world our beautiful baby boy. 29.12.15."
Earlier today, she also tweeted: "Waking up a mummy on my birthday is the best present anyone could ever wish for." Aww!
Following the birth, Sam's sister and TOWIE co-star Billie took to Instagram and shared her delight with fans.

She said: "I am the proudest sister and auntie in the world @samanthafaiers1 and Paul.
"I cannot describe my love for my beautiful nephew... I love you all so much and I can't wait for all the wonderful time we are going to spend together with him and Nelly."
We bet Billie and her daughter Nelly were first at the door this morning to help with both birthday celebrations and baby cuddles!
Meanwhile, there must be something in the water in Essex, as former TOWIE star Cara Kilbey has also been talking all things baby on her social media profiles.
Cara and her partner Daniel are expecting a little bundle in just five weeks time and last night she shared a gorgeous picture of her blooming bump.
Aww, Happy New Year to you all!
