STACEY Solomon couldn’t stop laughing as she watched her son Rex pee all over her sister who was changing his nappy in Pizza Hut.
The Loose Women presenter filmed her sister’s soaking wet jeans and T-shirt after Rex’s accident in the restaurant.
She had admitted being dragged out of the house for lunch with her newborn, but only if sister Jemma could do Rex’s nappy change.
Filming the hilarious moment, Stacey told followers: “My sister has forced me out shopping.
“She’s just changing Rex’s bum in the middle of Pizza Hut.
“I told her I’ll only come out the house if you change his bum.”
Stacey mocked her sister over the embarrassing moment, making her stand up to show off the huge wet stain.
“It’s so much worse than I thought”, laughed Stacey.
Last week the mum-of-three left the house for the first time in four weeks since giving birth to Rex.
The 29-year-old star previously admitted that she was scared to go outside with her “vulnerable” newborn in case it was too “dirty”.
But she was forced to push herself to go out for a walk while her boyfriend Joe Swash was away in Italy.
She couldn’t wait to have him home and celebrated his return by sharing a cute picture of him with Rex.
The TV presenter had been away on a cruise with Disney for the past fortnight, leaving behind his newborn son.
Unfortunately for the former EastEnders star, Rex shared his his first smile while he was away.
He wrote on Instagram: “How is my luck. I had 2 go away for work and Rex has his first smile, gutted.”
After he’d finally got back, Stacey told fans: “Daddy’s home – love the summer but I’m so glad daddy’s home and it’s cooled down now and we can all relax!
“P.S any advise on how to keep them cool in this heat would be much appreciated”
