Videos of Charice singing Houston's songs have gone viral on the Internet and were said to have been created on February 13, two days after Houston was found dead in a hotel in Los Angeles.
But Charice said in a phone interview with ABS-CBN News that these were old videos.
"Medyo mali nga 'yung ibang information. 'Yung iba sa kanila sinasabi na kagabi lang daw. Actually, 'yung video nga na 'yan 'yung iba last year, 'yung iba like 2009," she said.
For instance, a video of Charice crying while performing "I Have Nothing" was from the last stop of the U.S. tour of "David Foster and Friends."
Foster is Charice's record producer and also the composer of the Houston hit from the movie, "The Bodyguard."
Charice said she became close with the other members of the tour and that's why she became emotional during her performance.
But Charice said she is planning a tribute to Houston as part of her upcoming concert tour in Asia.
"Gusto ko pong maging special siya talaga. Pero syempre talagang gusto kong gumawa ng something para po sa kanya," she said.
"Maybe magiging emotional, kasi ang hirap pa ring tanggapin, kasi parang nawalan ka ng kamag-anak. I mean na-discover po kasi ako kasi syempre dahil kinakanta ko 'yung mga songs niya," she explained.
Charice said it was her dream to do a duet with Houston onstage.
But after Houston's death, Charice said she's content with the memory of meeting her idol backstage at an event one-and-a-half years ago at the Beverly Hilton Hotel -- the same hotel where Houston was found dead.
"Sobrang bait po niya, as in nanginginig ako that day dahil kilala niya ako," Charice recalled.
"Sabi niya napanood niya ako sa DVD tapos nag-jojoke pa siya. Sabi niya kinanta mo 'yung mga kanta ko na effortless. Kaya everytime na-iisip ko siya, talagang naiisip ko yung nag-meet kami dahil sobrang bait niyang tao," she said.
While Charice said she is aware that many compare her powerful voice with that of Houston, she said she is honored just to keep the songs of her idol alive.
Charice said she will return to the Philippines in March to do a concert. --
