Frankie and fiancé Wayne Bridge welcomed their bundle of joy into the world earlier today.
The baby boy weighed 7 lbs 13 oz and mother and baby are said to be healthy and happy.
Frankie announced her pregnancy earlier this year, shortly after revealing her engagement to footballer Wayne. The pop star started dating Wayne in December 2010.
With a new baby to look after, Frankie will certainly have her hands full! Luckily, she will have the help of her band mates as she settles into motherhood.
Frankie's fellow Saturdays were quick to send their congratulations tweeting that they couldn't wait to meet him.
Frankie’s newborn will be the first boy in The Saturday’s growing brood. Bandmate Una Healy has a young daughter, Aoife Bell, with husband Ben Foden. Rochelle Humes recently gave birth to daughter Alaia Mai with husband, former JLS singer Marvin.
The Saturday’s tour bus is set to be baby central as the new mums all continue to juggle raising their families with band duties.
Frankie’s new arrival is just one of many new babies in what seems to be a celebrity baby boom.
