Originating from Liverpool in 1998, Atomic Kitten is a British pop girl group with Liz McClarnon, Jenny Frost, and Natasha Hamilton as current members.
In 2006 and 2008, the trio briefly reappeared before the ITV2 show "The Big Reunion" reunited McClarnon, Hamilton, and Katona with fellow pop acts B*Witched, Five, Liberty X, Honeyz, and 911. Frost couldn't join then but rejoined in 2021. They released a rendition of "Whole Again" titled "Southgate You’re the One (Football’s Coming Home Again)" for UEFA Euro 2020. In November 2021, the group confirmed Frost's full-time return and their upcoming support for boy band Blue's 2022 arena tour.
