The mum of five, 39, is believed to have been in hospital since early this week, for reasons unconfirmed.
After sharing selfies on her Instagram stories earlier this week with her boyfriend Ryan by her hospital bedside, she's now shared a slew of snaps that show her being supported by her friends and family.
Kerry shared a selfie with her daughter Dylan-Jorge, five, from her hospital bed and captioned the pic: "Awww look who's come to see me!!!! One out of my five!!! Will let @123_mollymc off as she does live in another country 😂🤦♀️."
Fans rushed to send Kerry well wishes and wondered what was wrong with the former Atomic Kitten star.
Wishing you a speedy recovery.
One wrote, "Wishing you a speedy recovery and another asked, "What, you're in hospital? Are you OK? Sending you prayers and well wishes."
Kerry then followed up the heartwarming picture with three pictures of her church friends.
She explained that they'd come to visit her shortly after completing their charity walk in aid of the anti-slavery organisation Walk for Freedom.
Clearly delighted with their visit, Kerry captioned the pictures: "I got a lovely visit yesterday from these three crazy ladies.
"They had just done the #WalkForFreedom and came to cheer me up!! Bless them. Gutted not at church with you today ladies! For more info A21.org/Walk."
Back in August, she shared with her social media followers that she'd found God shortly after the death of her former partner and father to Dylan-Jorge, George Kay.
She also revealed in her New! magazine column that she was attending the London branch of Hillsong Church, whose Los Angeles branch is frequented by the likes of Justin Bieber and Chris Pratt.
Kerry wrote: "I really do believe I've found a new lease of life through going to Hillsong Church every week.
"I've always been very spiritual and I was raised a Christian, but in recent months I've experienced a lot of happiness in attending the services and learning more about Jesus, especially in the wake of George's death."
