Stacey already has son Zachary, 11
and Leighton, six, from previous relationships and she made sure to spend some one on one time with her eldest during their Easter break.
Taking to Instagram on Sunday, Stacey shared the adorable snap of her resting her head against Zachary as they laughed near a pool waterfall.
Stacey showed off her growing bump in a red two piece with side tie detailing, and captioned the image: "Spending some time with mummy all to himself before he has to share me three ways.
"He’s been sharing me with his little brother for nearly 7 years and he’s been incredible.
"So we are getting some memories in during the calm before the storm love u Zachy.
"P.S He’s laughing because he thinks my boobs are way too big and embarrassing for me to be cuddling him."
Stacey hasn't let her pregnancy slow her down, but admitted her busy schedule had taken its toll on Friday before her trip abroad.
The Loose Women star had headed up to Birmingham for the launch of the UK's largest Primark store.

“Wonderful as it was I can’t tell you how happy I am to be home, in my Winnie The Pooh Pyjamas and fully able to communicate with the boys properly again without distorted eyebrow movements and nose flares (if you know what I mean).”
