LOS ANGELES, Calif. - One of the last people to share a stage with Whitney Houston was R&B singer Kelly Price, who stopped on the Grammy Awards show's red carpet Sunday night to reminisce.

While others have said the singer appeared disheveled when she showed up Thursday to rehearse for music mogul Clive Davis' pre-Grammy party, Price said that wasn't the case when she saw her later Thursday at a party in Hollywood where the two sang together.

"She stood on her feet for over three hours, she cheered on every singer that hit the stage," said Price, who sang a duet with Houston on "Yes, Jesus Loves Me."

When she wasn't singing, Price said, Houston was dancing, either by herself or with others, including her 18-year-old daughter, Bobbi Kristina Brown.

"We had a wonderful time," Price said. "She celebrated me. She told me she was proud of me, she told me she loved me,"

The pair's friendship dates to 1998 when Houston heard Price on the radio and invited her to sing with her on "Heartbreak Hotel."
