According to TMZ, Celine Dion and Lady Gaga will sing a duet during the opening ceremony tomorrow night.
The usually well-informed American entertainment site writes that the two singers will sing the song La vie en Rose by Édith Piaf together.
Rumors about a performance by Dion and Lady Gaga have been going around for a while.
The artists were spotted separately in Paris in recent days, where the Olympic Games are taking place this year.
For the 56-year-old Dion, it would be her first performance since she revealed that she suffers from stiff-person syndrome, as a result, she canceled a world tour.
In her documentary I Am: Celine Dion, the singer shared a while ago that she is working hard on a comeback on stage.
