Host Jimmy Fallon opened the show with words about the tragedy stating, "This morning, we woke up to the news of another senseless shooting. This time in Las Vegas. In the face of tragedies and acts of terror, we need to remember that good still exists in this world. We're here to entertain you tonight, and that's what we're going to do."
"There's no love without freedom," they duet in the chorus. "No freedom without love."
The 'Malibu' singer helped Fallon close the show by performing 'The Climb,' a heartfelt number from 'Hannah Montana: The Movie.'
At least 59 people were killed and hundreds injured in the mass shooting in Las Vegas on Sunday.
