The tribute is a fitting role for singer/actress Sparks, who plays Houston's daughter in the upcoming remake of the film Sparkle, which hits theaters in August.
Houston, who died Feb. 11 at age 48, holds the distinction of being the first artist ever to have seven consecutive No. 1s on the Billboard Hot 100 and her biggest hit, "I Will Always Love You," spent 14 weeks atop the chart in 1993. She earned 16 Billboard Music Awards, six Grammys, 23 American Music Awards and two Emmys, and has sold 170 million combined albums, single and videos worldwide.
