Jennifer Hudson Whitney Houston Split - H 2012

Grammy Awards crew who witnessed the "American Idol" alum rehearsing tell THR, "She's having a hard time."

Jennifer Hudson deserves all the praise the music industry can muster today as she prepares to pay tribute to Whitney Houston, the R&B superstar who was found dead in her hotel room on Saturday afternoon, hours before she was due to make an appearance at the annual Clive Davis pre-Grammy gala.

Not surprisingly, Hudson is said to be "having a hard time" at rehearsal for the tribute number, which will air three-quarters of the way through the broadcast, as part of a broader "In Memoriam" segment. She is singing Houston's monster hit "I Will Always Love You."

A Grammy crew member tells The Hollywood Reporter that Hudson was "crying and had to keep pausing" to collect herself during the Sunday afternoon rehearsal (the show kicks off at 5 p.m. PST). "She was having a hard time getting through the song, especially on the second run-through."

Chaka Khan has also been added to the tribute number with possibly more surprise guests to be announced.
