Frost, who replaced Katona in the band in 2001, admitted that she had heard rumours about a full reformation for the girl group but would never become involved in such a move.
"I read that we're supposed to be getting back together with Kerry," she told Closer. "But I'd rather eat my own kidney with a spoon!"
Atomic Kitten released three studio albums and scored 13 top ten hits between 1999 and 2005. After Frost joined the band, they reached number one three times with 'Whole Again', 'Eternal Flame', and 'The Tide Is High'.
Liz McLarnon, Natasha Hamilton and Jenny Frost reformed in 2008 to release a cover of Cilla Black's 'Anyone Who Had A Heart', but it failed to break the top 75. They disbanded again shortly afterwards.
