Whitney Houston’s last film appearance was in the movie Sparkle, which hits theaters next month, but you can have a little part in celebrating the great diva with a song competition. On Saturday at Valley View Mall, amateur singers (ages 13 to 40) can register to sing a 60-second version of “Celebration” or “Something He Can Feel.” The winner locally gets not only $500 in cash and a $25 bebe gift card, but also gets entered in the grand prize: A trip to New York City and an appearance on BET, plus more. Registration is at noon, with the contest promptly beginning at to 1 p.m. You can go here to see clips of the songs you can sing, and pre-register your slot by emailing DallasSingingChallenge@moroch.com. Complete rules are here.
