Melanie Blatt Young Theatre School where she met Nicole Appleton. The two girls became best friends. During this period, Blatt also played young Eponine in "Les Misérables" for six months, and was the understudy for Cosette together with fellow Sylvia Young student Denise van Outen. In 1993, Blatt sang under the name Melanie Guillaume in the band Drive with Julienne Davis. They released one single, "Curfew", together. She also did backing vocals for Dreadzone with Denise van Outen. Later that year, Blatt met Shaznay Lewis at the Metamorphosis recording studio in All Saints Road, London. Together, with Simone Rainford, they formed the
All Saints (group) the singers playing three street-wise, saucy sisters who head "up West" to pursue a life of crime. The film received attention for the Appleton sisters topless scenes. Their performances were widely panned; one critic remarked, "It is the worst kind of rubbish, the kind that makes you angry you have wasted 105 minutes of your life watching it." In October 2000, All Saints released the single "Black Coffee", which became their fifth and final number-one single in the UK, selling 200,000 copies. This preceded their second studio album, "Saints & Sinners", which debuted at number one on the UK Albums
