It's recently been revealed that Girls Aloud are reuniting and releasing a new single in memory of their late band member Sarah Harding, who died of cancer in 2021.Their single is the first since their 2012 track Beautiful 'Cause You Love Me.The video is said to feature the stars dressed as superheroes, as a source told The Sun: "This has been one of the best kept secrets in pop, but it's actually happening now. "The girls really came back together as friends to rally around when Sarah died, and it repaired some of the old rifts and put things into perspective. Suddenly the reunion which had seemed totally impossible for so long just felt a totally natural thing to do- in Sarah's honour.The insider added: "It's going to be huge - and they're all very excited to be back working together, even if there is a bittersweet element to it.
