"We Can't Be Friends," a duet with R. L. Huggar, reached the top ten, with "It's Over Now" and "I Never Knew" become chart-toppers on the Dance Club Songs chart. 2000–2005: The Morning After and acting career After One Wish, Cox collaborated with singer Whitney Houston on her single "Same Script, Different Cast" from the compilation album Whitney: The Greatest Hits. Incorporating a backing track of Ludwig van Beethoven's "Für Elise" during the intro, it was released as a radio-only promo single and became a minor hit on Billboard Hot 100, peaking at number 70 while reaching number 14 on Hot R&B/Hip-Hop Songs. In 2000, Cox made her acting debut when she starred in Clement Virgo's Canadian drama film Love Come Down, playing a nightclub singer. The film garnered eight nominations at the 21st Genie Awards, including two Best Original Song nominations for Cox's songs "29" and "Our Love". In 2001, Cox then recorded "Absolutely Not", for the soundtrack to Dr. Dolittle 2 which became her sixth number one hit on Billboards Dance Club Songs. Cox's third album The Morning After was released in November 2002 on J Records following a frustratingly long departure from Arista. It marked the Cox's first record under Clive Davis's label, with Davis, once more serving as executive producer. Keen to build on the success of her previous album One Wish, he enlisted the help of producers such as Jimmy Jam and Terry Lewis, Jermaine Dupri, Rodney "Darkchild" Jerkins, and Shep Crawford as well as up-and-coming producers Warryn Campbell, Johntá Austin and Alex Richbourg to work with Cox. A blend of urban R&B and adult contemporary songs with additional dance/house tracks, it became her highest-charting album on the US Billboard 200 and Billboards Top R&B/Hip-Hop Albums yet, debuting and peaking at number 38 and number seven, respectively. Commercially, the album was less successful than her previous album, however, though it produced two singles on the US Dance Club Songs chart, including "Mr. Lonely" and "Play Your Part". In February 2004, Cox made her Broadway debut in the Elton John-Tim Rice musical Aida when she replaced singer Michelle Williams in her role of the Nubian princess. Her four-month engagement earned largely positive reviews. The same year, she recorded and released a dance remix of the musical's theme song "Easy As Life" as a promotional single. In 2005, Cox starred in the films Blood of a Champion
