Mrs Hinch has confirmed she's expecting "baby number two" with her husband of three years, Jamie Hinchliffe.
The cleaning whizz, 30, whose real name is Sophie Hinchliffe, welcomed her first child, son Ronnie James, in June of 2019.
Making the announcement, little Ronnie was asked to pose with a message board in his hand, which featured a print of the baby's ultrasound.
The words "New Year's resolution, be the best big brother, 2021" were written in block lettering on the board.
In her caption, Sophia opened up about the baby news, saying: "It is often in the darkest skies that we see the brightest stars.
"Baby Hinch Number 2, We can’t wait to finally meet you.
"Happy New Year everyone... from our little family to yours... We hope your 2021 is filled with hope, health and happiness. We love you all."
Another photo showed Sophie cradling her baby bump, with a string of ultrasound photos dangling from one hand.
Sophie's celebrity pals were quick to send their messages of congratulations in the comment section below, delighted by the news of their growing family.
Love Island star Molly Mae Hague wrote: “OH MY GOD STOP !!!!! congratulations!!!!!!”
“Awwwwwww congratulations,” added TOWIE star Georgia Kousoulou, who is also expecting a baby.
And Loose Women panelist Stacey Solomon added: "Luckiest handsomes in the whole wide world. We love you to the moon and back. Ron you are going to be the best big brother ever. Yes 2021. Soph, the most incredible mummy, I love you."
The delighted parents tied the knot in 2018, with Jamie proposing to his wife-to-be on their fourth anniversary.
Planning a summer wedding, the lovebirds said "I do" in Gosfield Hall, a former royal residence in rural Essex.
Later that year, the newlyweds confirmed they were expecting their first baby together, making the announcement on Christmas Day.
At the time, she said: “Mr Hinch and I have been keeping a little secret.
“All of our Christmas wishes have come true, our mini Hinch will soon be due. Henry is going to be the best big brother ever!
“I hope you’ve all had the most magical Christmas Day.”
Little Ronnie was born in June of 2019, as proud dad Jamie expressed: "I didn’t think I could love Soph any more than I already do, but I was so very wrong."
