Kerry Katona doesn't think she's fit enough for Atomic Kitten's tour

Kerry Katona is doubting her fitness levels for Atomic Kitten’s comeback tour.

The 34-year-old singer recently admitted she had put on a stone since giving birth to fifth child Dylan-Jorge last April and she is confided in her bandmates she is worried she won't be able to handle the gruelling dance routines of a live show.

Her bandmate Liz McClarnon said: "I broke the news to Kerry that being on tour means we will be on stage for an hour and a half without an interval, and her reaction was hilarious.

"She kept saying how exhausted she is going to be and she's worried it will be harder than she remembers from before."

However, Liz says Kerry has upped her training schedule and is working hard to ensure she is fit for the shows.

She added: "Kerry is training a lot and eating very well - she is determined to succeed. She's looking amazing for it too."

In contrast, Liz is struggling to deal with the pressure of the tour, which will see the 'Whole Again' singers visit Europe, Asia and Australia.

"I have been suffering from panic attacks caused by lack of sleep and feeling under pressure,” she told Closer magazine.

"I ended up falling asleep in the day and being awake at night. I got myself into a vicious cycle but I am feeling better now."

At least she can take a break for this number:
