The reunion comes after Kimberley admitted that Girls Aloud are ‘feeling outside pressure’ to reform for the band’s upcoming 20th anniversary.
Speaking on The One Show earlier this month, the singer explained: ‘It’s 20 years in 2022 so we’re feeling a bit of outside pressure now.
‘People keep asking if we’re making any plans and we actually haven’t made any yet, but we’re definitely feeling a bit of pressure from the outside so you never know.’
