Pregnant Stacey Solomon grinned from ear to ear before heading out on a 'date night' in her fluffy mule slippers with her youngest son Rex.

But the cheeky tot won't be her youngest for long as she's soon expecting her first daughter with partner Joe Swash.

Until then Stacey is soaking up all the 'mummy cuddles' from her adorable son Rex as she revealed when sharing lots of stunning shots of their adorable 'date night' together on Instagram.

She posted: "Date Night. Off out with my littlest pickle who won’t be the littlest pickle for much longer. I love you darling boy, to the moon and starts and back again.

"You make my smile bigger and my heart happier. You’ll always be my baby just like your big brothers."

And in her usual funny charm the star added to her followers: "P.s These pictures look so lovely and natural but the truth is he just wanted to get my boobs out the whole time. These were the only ones where I wasn’t flashing. Happy Sunday Everyone."

The mum-of-three previously told how she's adjusting to a week with just Rex and Joe at home in her plush Essex pad, as her oldest son's Leighton and Zach are spending the week with their dad's.

One fan gushed: "Ahhhhhh my actual heart. how is Rex always THAT HAPPY."

Another added: Aw I love this both stunning enjoy your date night."

A third simply posted: "You are glowing."

Rex is the 'perfect' date night companion

And The Saturdays singer turned DJ, Mollie King was one of the first to comment adding: "Beautiful photos! That caption made me laugh!"

The Loose Women panelist looked gorgeous in a blush and white bodycon dress which stretched to make way for her growing baby bump.

She let her long locks cascade off her shoulders as son Rex perched behind her and weaved himself into her off the shoulder outfit adding to the adorable giggles.

Rex wore beige chino-style shorts and short sleeved shirt but the outfit was capped off with a straw hat which covered his waist-length blonde curls.

Rex was singing for his supper at the posh pub!

The pair headed out for a Sunday Roast as fiancee Joe stayed home with a headache and tooth problems so was going to 'sleep it off'.

Stacey later shared a Instagram story revealing she'd forgotten her shoes instead wearing comfortable fluffy mule slippers, for the date night at a busy 'posh' pub after she couldn't get a spot at a child-friendly carvery.

She quipped: "Unfortunately Rex's dinner chat isn't suited to posh places."
