Lady Gaga, Celine Dion add sparkle to star-studded Olympic show

Lady Gaga, Celine Dion and French-Malian singer Aya Nakamura joined dancers, an opera diva and even a heavy metal band in an opening ceremony for the Paris Olympics that sought to proudly showcase French culture with a modern twist.

The first-ever opening ceremony held outside a stadium -- on the River Seine -- had to battle driving rain that cast a pallid gloom over the City of Light.

The fast-moving and multi-location ceremony masterminded by acclaimed French theatre director Thomas Jolly was aimed at impressing the global TV audience as much as those who braved the weather and intense security to watch live.

"It is now. The world is watching us. Let's open the Games in style!" French President Emmanuel Macron, who watched the ceremony in a VIP stand with other leaders, wrote on X, formerly Twitter.

In a nod to her passion for French culture, Gaga appeared from behind a fan of pom-poms held by her dancing troupe to sing Mon truc en plumes (My Thing With Feathers), an iconic French music hall hit by the legendary Zizi Jeanmaire.

"It is my supreme honour to sing for you and cheer you on," Gaga wrote on her social media channels after the performance, saying she always "felt a very special connection with French people and singing French music."

Franco-Malian R&B superstar Aya Nakamura, the most listened-to French-speaking singer in the world, performed a medley with two of her hits Pookie and Djadja and a classic by Charles Aznavour, For me Formidable, one hundred years since his birth.

Canadian singer Celine Dion, who had been battling a rare illness, made a spectacular comeback by singing from the Eiffel Tower at the climax of the ceremony with a rousing version of the Hymn to Love by Edith Piaf.

According to Jolly, the 12 different phases of the ceremony told the story of a country rich in its "diversity", "inclusive", "not one France but several Frances", and celebrating "the whole world united".

In another highlight, the star "etoile" dancer of the Paris Opera, Guillaume Diop, performed on a Paris rooftop.

For many French spectators, the highlight was the surprise appearance of the heavy metal group Gojira, who burst out onto platforms constructed on the Conciergerie, a key building in the French Revolution, where deposed queen Marie-Antoinette was held.
