Dozens of fans cheered and applauded as music icon Celine Dion left her hotel in Paris on Saturday (July 27) to leave France after her widely praised performance at the Olympic Games' opening ceremony on Friday (July 26).

Dion surprised fans, some of whom had been waiting for hours to take a photo and ask for an autograph from the Canadian singer, outside the Royal Monceau hotel in Paris as she climbed out of her car's sunroof and sat atop the vehicle as it drove away.

"Actually, I'm still very, very emotional, not about my performance last night but about how the athletes have been feeling in this whole thing (Olympics)," Dion told Reuters. "I would love to say goodbye properly because I haven't been here for so long."

A household name in France, Dion sang Edith Piaf's "Hymn to Love" at the Games' four-hour opening show in her first public performance in years, drawing huge cheers from the crowd.

France's three-time Olympic gold medallists Marie-Jose Perec and Teddy Riner then lit the Olympic cauldron, suspended on a hot-air balloon during the show.

Dion's fans said they were ecstatic to have watched their favorite artist perform again, especially during the Olympics.

"It's true it (Dion's Olympics performance) was the comeback that we had been waiting for... Honestly, that's the best international comeback that she could have made," fan Mickael, who cut short his vacation in southern France to come and try to get a glimpse of Dion in Paris.

Fan Gabrielle Garnier said she welled up with tears when she saw Dion's performance.

"When we saw her singing, giving such a performance, we couldn't help but cry, really. And I think Celine Dion was the person, among so many others, who could best represent France," Garnier said.
