The 38-year-old Atomic Kitten singer has returned to the UK following her tour Down Under with her bandmate Natasha Hamilton and Liberty X's Michelle Heaton - who temporarily joined the kittens to make up the trio in the place of Liz McClarnon for the shows in Australia and New Zealand.

But the band's hectic schedule appears to have taken its toll on the mum-of-five, who is suffering from an illness which has left her feeling dreadful.

Kerry took to Twitter on Thursday (23.02.17) to reveal: "Just been the doctors & have a viral infection! & just had a quarter zone injection in my shoulder!I'm falling apart!Need a MOT #keepsmiling

"Feel sooooo poorly! Followed by an unhappy emoji (sic)"

The blonde beauty feels so ill that even her "thumbs" are "aching".

She added in another tweet: "My whole body is aching!! Even my thumps when texting! Think living out of a suitcase for 3 weeks has caught up with me! (sic)"

And bandmate Michelle isn't feeling great either - she is battling extreme jet lag from the long haul flight home.

She tweeted: "Hello 4am wide awake club 3rd morning in a row #jetlag #tourlife."

To which Kerry replied: "Michelle I feel like (poo emoji) it's hit me like a ton of bricks!"

Michelle replied: "Lol tell me about it x."

Meanwhile, Natasha claims her jet lag is influencing her poor diet choices.

She posted on Twitter: "My food diary day - bacon butty @ 5am, coffee & carrot cake slice @ 10am, salmon & salad lunch 1.30pm...fuming with myself...I blame jet lag (sic)"

Earlier this week, Kerry was reunited with her husband George Kay and her children - Molly, 15, and Lily-Sue, 14, her daughters with Brian McFadden, Heidi, 10, and Maxwell, nine, her kids with Mark Croft, and two-year-old daughter Dylan, who she has with George.
