The 48-year-old "My Heart Will Go On" hitmaker said she is freaking out about the song, reported Entertainment Weekly.
"I can't really talk about the other writers yet because nothing has been confirmed, but trust me, I hope that Sia and Ne-Yo and Bruno Mars and all the people that we love, oh my gosh, I hope they write for me.
"Are you kidding me? I can just give you a little hint: Pink wrote me a song that I'm freaking out about," Dion said.
"You cannot be more excited than me, I'll tell you. I am thrilled not only because I am a fan, but because I know her personally and have met her a few times. She's a genuine person and (it was) so generous of her to take the time to write a song for me during the most difficult time of mine.
"People have a tendency to send me really sad songs, and we do want to sing the touching songs, but life is beautiful, and I really want to believe that Rene has a life after his life, that he doesn't suffer anymore," she said.
