Squeezing a personal training session into her busy schedule, Frankie was all smiles with Parker by her side and couldn't resist posing for a snap to prove just how cute her little man is.
Giving her fans a proper glimpse of four-month-old Parker, Frankie lay down and propped him up in front of her for the photo.
She added the caption: "This little guy joined @reshapeology and I in training today! He passed the time nicely."
In the snap, tiny Parker is seen wearing a white and black outfit while his yummy mummy is dressed in all-black gym gear and has her short hair clipped up.
The mother and son have spent a lot of quality time together this week, as Frankie took Parker for a walk in the sunshine recently too, along with one of the family dogs.
As well as her parenting duties, Frankie has been busy filming a new music video for The Saturdays' latest single 'Not Giving Up'.
She and her bandmates Rochelle Humes, Una Foden, Mollie King and Vanessa White all decided to officially release the track after it became a fan favourite.
Frankie said: "We listened to all you fans and know you all love it so it was a bit of a no-brainer for us."
'Not Giving Up' drops on 7 April. Watch the video below.
