During part two of Oprah's 2009 season premiere interview with Whitney Houston, Celine taped a special message to pay homage to this music icon.

"You know I grew up listening to you and everything you sang inspired me," Celine said. "Your music really touched me deeply. I'm so happy that you're back."

Celine wasn't the only singer to express her love for Whitney. Other well wishers included Jennifer Hudson, Christina Aguilera and Dionne Warwick.
