ROCK OF AGES: Celebrity guests including Katy Perry, Elisa Sednaoui, Poppy Delevingne, Zhou Xun and Michelle Chen marveled at the glowing crystal-studded set that Karl Lagerfeld dreamt up for his Chanel show at the Grand Palais on Tuesday. “At first I thought it was icicles, but now I realize that it’s really amethysts, and that’s just so much more beautiful and powerful,” said Alicia Keys, who claimed to know a thing or two about crystals.

“Every time I discover more of the meaning behind them, you realize how much they can have an impact on you,” said the singer, who was wearing an Indian style pendant over her forehead. “I think the Earth is such a powerful thing and we don’t recognize all the things that come from it and what type of power they hold, and I think he does,” added Keys, referring to Lagerfeld.

“It’s very purple, I love the amethyst theme,” enthused tattooed Canadian singer Béatrice Martin, aka Coeur de Pirate, noting she’ll soon be winding down her touring, as she is three months pregnant.

Virginie Ledoyen knows something about amazing locations. For “Farewell, My Queen,” the Marie Antoinette drama scheduled for release in France later this month, she got to spend time at the royal château in Versailles. “When you are all alone in the Trianon, waiting in Marie Antoinette’s chambers, you very easily let yourself get swept away,” said the actress, who plays Marie Antoinette’s confidante, Gabrielle de Polignac.

Kaya Scodelario was making a pit stop in Paris before flying back to Los Angeles to complete shooting opposite Jessica Biel and Alfred Molina on the movie “Emanuel and the Truth about Fishes.” “I go for a good title,” she quipped. Also look out for the “Skins” actress in “Now Is Good,” the story of a girl suffering from leukemia (played by Dakota Fanning) who makes a list of things to do before dying.

Brazilian actress Laura Neiva is preparing to return to Cannes in May to present a short film. It won’t be her first time at the prestigious film festival: Neiva was just 15 when she walked the red carpet with Vincent Cassel for her debut film “Adrift.” Her next feature film is a romantic comedy called “E aí, Comeu?” (“What’s Up, Did You Eat?” in English), which will be released in Brazil in June.
