Dions support did not go unnoticed by Gaga, who sang her praises to the audience.
Give it up for Celine Dion, Gaga told the crowd at one point.
She prayed with me and my entire crew backstage before this show.
That is how amazing she is.
Youre supportive, youre talented, youre legendary, and youre kind.
And I sang your songs over and over again as a child.
I told you backstage The Prayer with Andrea Bocelli is one of the most beautiful songs of all time.
Gaga then dedicated her next song, You and I offBorn This Way,to Dion.
After the show, Dion shared a video on Twitter of herself dancing in the crowd.
I had so much fun last night @Ladygaga!
Your energy on stage is contagious and you literally took my breath away!
I wish you all the best with your #Vegas residency!
