Charli XCX has revealed that she wrote some new music for Britney Spears, but said it was never recorded.Late last year, it was reported that the singer-songwriter was working on material for Spears’ comeback album – the pop star’s first since 2016’s ‘Glory’. Charli had previously penned songs for Spears’ 2013 record ‘Britney Jean’, although none made the cut.During a recent appearance on Watch What Happens Live With Andy Cohen, the ‘Von Dutch’ artist confirmed that she had written something new for Spears.“It leaked to the press. Britney then did this post where she was like, ‘I don’t have random people write for me’,” Charli explained.
