The EastEnders actress, who is expecting her first baby with TOWIE star boyfriend Dan Osborne, recently turned 22 and marked the occasion with a meal last night.
Jacqueline invited all her closest pals to the meal and was pictured blowing out a candle on a yummy slice of cake after her friends had sung 'Happy Birthday'.
And although booze is strictly off the menu for the next few months, Jacqueline toasted her special day with a non-alcoholic drink.
Sharing a snap of her beverage on Instagram, Jacqueline told fans: "Cheeky mocktail #BENIHANA thank you ladies!!!"
In August, Jacqueline and Dan revealed that they are expecting a child together, adding that they are both "thrilled".
Since then, the couple have discovered the sex of their baby but have decided to keep tight-lipped.
Teasing fans Jacqueline and Dan cut into a baby shower cake to reveal either a pink or blue sponge - before sharing a black and white picture on Twitter.
