Arena's first French language single, "Aller plus haut" (English: "Go Higher", July 1999), appeared on the continental version of "In Deep", which peaked at No. 2 on the local singles chart; it has sold 600,000 copies in that country. It also became her first number-one hit on the Belgian Singles Chart. Her second French language single was a cover version of "Les trois cloches" (English: "The Three Bells", January 2000), which reached No. 4 in France and another number-one hit in Belgium. From May that year she lived in London while she appeared in the lead role of Esméralda for the stage musical, "Notre Dame de Paris" during a six-month run. Carr, by now her ex-husband, had claimed in "Business Review Weekly" (2000) that Arena was paid $200,000 per week when she was performing in "Notre Dame de Paris".
