The Saturdays star, 26, uploaded the sweet picture to her Instagram account on Tuesday morning underneath the caption: "Just the 3 of us."
Frankie's blossoming baby bump is clearly on display as she's wearing a white bikini in the snap, which appears to be taken abroad.
We're loving little Parker's sunglasses as well! He certainly looks like he's enjoying his first ever holiday!
Frankie and former footballer husband Wayne Bridge are expecting their second child in mid-August and have already confirmed it will be another boy.
She's said little Parker, 19 months, is too young to really understand what is happening right now but we bet he'll love having a little brother to play with!
Frankie didn't have the easiest start to her pregnancy after suffering from hyperemesis gravidarum, the severe pregnancy sickness that also affected The Duchess of Cambridge.
