Her signature song is "My Heart Will Go On", the Grammy-winning love theme from Titanic.
The singer previously teased that we would be hearing new music from her soon, but none of us expected this.
As Dion performs the lovely ballad, Deadpool himself makes an appearance. And the talented pair make quite the impressive duo.
