Earlier this year Kerry revealed her mum Sue was in hospital after suffering a heart attack.
Kerry wrote on Instagram: "my mum is doing well and is in the best place!! Gave us all a massive scare xxxxxx."
She added that the whole family is "shook up".
Seven years ago she revealed Sue had been diagnosed with a serious heart condition that could lead to angina and a heart attack.
A source said at the time: "They've had their differences over the years but they are very close and Kerry would be devastated if anything happened to her mum."
Last year we revealed how Kerry was moving closer to Sue because of her health problems.
It comes shortly after Kerry fans all said the same thing after her daughter Lilly-Sue shared a selection of glamorous snaps with fans.
The teen took to Instagram to post the stunning pictures.
Fans rushed to the comments section to praise her beauty, but others couldn't help but point out how much she looks like her famous mum.
One wrote: "Beautiful 😍 just like your mum ❤️."
A second said: "Wow 🔥🔥🔥 your the double of your mum 😍."
Lilly-Sue is the daughter of Kerry and her ex Brian McFadden.
The pair were married for two years before they split in 2004.
They also share 20-year-old Molly Marie.
Kerry is also mum to Heidi Elizabeth, 15, and Mark Maxwell, 14, who are from her marriage with Mark Croft.
The star's youngest, Dylan-Jorge Rose, eight, is from her relationship with George Kay.
