Family comes first.
Warwick's show at The Palace Center in Greensburg, Pa., will be pushed to March 2.
Another star affected by the loss of a legend? Houston's Waiting to Exhale costar Angela Bassett...
"I am so thankful to have been enveloped by the warmth of Whitney's great talents," Bassett said in a statement. "They were undeniable and vast. Whatever her burdens, she has at last laid them down and picked up instead a crown. For truly, she was and will ever be for us, who were so captivated by her strengths, unparalleled."
Fellow vocal powerhouse Céline Dion remembered Houston as "an amazing inspiration," when she called in to Good Morning America on Monday. And while the official cause of death has yet to be determined, Dion seems to have her own guesses.
"It's just very unfortunate that drugs and, I don't know, bad people or bad influences took over," she said. Houston was open about her own addiction issues throughout her life. "It took over her dreams, it took over her love and motherhood…I mean, you think about Elvis Presley, Marilyn Monroe, Michael Jackson, Amy Winehouse, to get into drugs like that for whatever reason, is it because of the stress, the stress and bad influence, what happens?"
Whatever the cause of Houston's death, the feeling is the same: we lost a true talent far too soon.
