Just one night before she passed away, Whitney Houston took to the stage to sing "Yes, Jesus Loves Me" at the Kelly Price & Friends Unplugged: For The Love Of R&B bash at Tru Hollywood. Cell phones captured the video, which is now making it's way around the internet.

According to NBC the singer, 48, had been expected to attend a pre-Grammy gala hosted by Clive Davis on Saturday night, but was found dead hours before the event. Paramedics attempted to revive Houston, but were unsuccessful.

Beverly Hills police Lt. Mark Rosen told reporters outside the Beverly Hilton that Houston was pronounced dead at 3:55 p.m. in her room on the fourth floor of the hotel.

"There were no obvious signs of any criminal intent," Rosen said.

Houston was discovered by her body guard in the bathtub in her hotel room. Reports say that prescription drugs were found, leading to speculation that the singer may have drowned.   At this time, cause of death is still unknown.
