The 32-year-old singer has been very hands-on with the creation process in the hopes of concocting the perfect scent, Daily Mirror.
"Sarah is really excited and has been very hands-on with the perfume, testing every ingredient personally. She doesn't want to do a One Direction-esque saccharine smell - she wants it to be classy," a source said.
Harding has been working with top perfumer Azzi Glasser and Medichem to create her own beauty range, 'By Sarah Harding', which will allegedly arrive in stores in time for summer.
