But her latest Instagram post might just be her cutest yet – as it shows Rex giving a full-on, proper smile to the camera.

Her followers, including her Loose Women family, were quick to reply, with Nadia Sawalha writing: "Soooooo smiley!!!" Ruth Langsford also commented: "ADORABLE! X."

Stacey and Joe welcomed their first child in May, revealing that their little boy arrived two weeks early. The family have been enjoying the summer off with their older children – Stacey's sons Zachary, 11, and Leighton, seven, and Joe's 12-year-old, Harry. They have just returned from a sun-soaked holiday abroad, where Stacey posted some adorable snaps of the siblings bonding.

Stacey also kept it real in another post, proudly showing off her post-pregnancy body in a black bikini. She captioned a photo of herself cuddling Rex in the sea: "I love my body. Every bit of it. Even the bits that society says shouldn't be there. Because EVERY bit of it came together to make him. And Zachary. And Leighton. Cellulite is beautiful, back bumps add character and tummy ledges are great for resting a baby on."
