They once shared a duet at New York's iconic Madison Square Garden.
And until today Celine Dion remembers the moment she brought out Charice, now known as Jake Zyrus, to sing "Because You Loved Me."
In a report by ABS-CBN News MJ Felipe Friday, Dion joked that she still hasn't gotten over that one time she heard that amazing voice live.
"My jaw is still dislocated 'cause the whole arena was blown away," she said when asked about their performance in 2008.
That was way before Charice came out as a transgender male — a decision that, Dion explained in the same interview, deserves respect.
Saying that finding acceptance for being oneself is difficult nowadays, Dion, referring to Jake Zyrus, urged everyone: "We have to respect that. I wish him the very best."
After the report aired on "TV Patrol," Jake Zyrus took to Twitter to react to Dion's kind words. "I will never forget you, that precious moment and your heart. Love you," he wrote.
Dion, best known as the powerful voice behind the enduring "Titanic" theme, "My Heart Will Go On," and many more hits, will be performing in Manila at Mall of Asia Arena on July 19.
Tickets are priced at P35,380, P32,210, P19,540, P16,370, P7,920 and P2,640, and will be available to the public on January 18.
