R&B diva Whitney Houston's upcoming greatest-hits album will feature a duet with British pop singer George Michael, the song's producer, Rodney Jerkins, told reporters at last week's Grammy Awards. The song will be a reworking of Houston's "If I Told You That," which appears as a solo track on her album My Love Is Your Love. Jerkins told MTV News that Michael Jackson was the first choice for the number, but "we couldn't get [that] to happen, so George Michael was the next pick." The LP, due in May, also will feature duets with R&B singer Deborah Cox and Latin-pop star Enrique Iglesias.
