Mum-of-four Kerry announced on The Alan Titchmarsh Show yesterday that she is expecting a baby with George, which will be their first child together.
The Atomic Kitten star has since been inundated with well-wishes from fans, friends and her Big Reunion pals over Twitter.
911's Jimmy Constable, Liberty X's Jessica Taylor and former Hollyoaks actress Gemma Atkinson were just some of the many who tweeted their congratulations.
Responding to a friend, Kerry said: "Aww thank you, we're over the moon xxxx."
As well as thanking everyone for their kind messages, Kerry also had to assure fans that she would still be performing with Atomic Kitten, as the group are set to go on The Big Reunion Christmas Party Tour in December.
And it seems like there will be plenty of baby talk on the tour, as Kerry isn't the only Big Reunion star expecting a child.
5ive's Scott Robinson, who is expecting twins with his wife Kerry, said: "Just got off the phone from @mrgsjkay and @KerryKatona7. Me and @Kerry_lou83 Are so happy for you guys Big reunion babies lol #blessed."
Meanwhile, Liberty X's Michelle Heaton, who is pregnant with her second child, tweeted: "Massive congrats to my little kitten @KerryKatona7 bumps go on tour! Whoop! X."
Posting a lengthy message on Twitter, Kerry added last night: "We all deserve happiness, sometimes it just takes a painful journey to help you find it, so that you can then truly cherish and appreciate it.
"Today I close the door to the past, open the door to the future, take a deep breath and step on through to start the next chapter in my life."
