The original Atomic Kitten line-up have gone back into the studio for the first time in 11 years, according to reports.
The Daily Mirror said that Kerry Katona was spotted leaving the Liverpool studio with Natasha Hamilton, 30, and Liz McClarnon, 31.
Kerry, 32, who has since had four children and been divorced twice, grinned alongside her former bandmates.
The newspaper said that a camera crew was also filming for ITV2’s Big Reunion show.
Atomic Kitten, 5IVE, B*Witched, Liberty X, Honeyz and 911 reform “for one night only” in the ITV2 show.
Each band has just two weeks of intense rehearsals before they step back onto the stage to perform once again in front of thousands of fans.
Kerry left the group while pregnant with her first child and was replaced by Jenny Frost before the band went on to have their first number one, Whole Again.
