The presenter posted the wonderful news on Instagram on Wednesday (December 28) with a beautiful video showing the moment she shared the results of a pregnancy test with Joe.
"You're joking," Swash says initially, before telling her it's "the best news".
In a caption, Solomon wrote: "Me + Him = 👦🏻👦🏼👦🏼🧒🏼👧🏼👶 So grateful & can not believe I’m saying this… Another little pickle is on the way… 😭 A HUGE surprise, but one that we are so thankful for to the moon & back bub."
Former Loose Women star Vicky Pattison added: "I'm sobbing, congratulations guys."
The couple have previously welcomed a son and daughter, along with Stacey having two children from prior relationships. Joe also has a son from a prior relationship.
This latest news comes a few months after Stacey and Joe tied the knot at their home 'Pickle Cottage' following an extended COVID-induced delay.
At the time, she posted on Instagram about the wedding: "The most special day that we didn't ever want to end. We love you all and the special community we've built on here so so much and couldn't wait to share these moments with you.
"Joe lost his father at the age of 11 and so did my dad. A huge part of our wedding day was reflecting on how this had a huge effect on them and how hard it is, even to this day to deal with."
Loose Women airs on weekdays at 12.30pm on ITV1.
