“They are so normal,” Carine Roitfeld told PEOPLE at the N.Y.C. premiere of the new documentary film, Mademoiselle C, on Friday. “They are lovely together.”
The film is about how Roitfeld started the edgy new CR Fashion Book after her 10-year run at French Vogue.
Kardashian, who sports a gold grill on the cover of the latest issue of Roitfeld’s magazine, was expected to make her first official post-baby appearance at the premiere and the afterparty at The Four Seasons Restaurant, but ended up canceling.
West, 36, did make it to the Absolute Elyx-sponsored fête – albeit quite late.
“He came because Carine is a good friend of his,” says a source close to the singer, who appears briefly in the film.
Roitfeld revealed that she met Kardashian, 32, through West “because he is so into fashion, of course.” “We decided we would do a story about her. Immediately she said, ‘Yes.’ ”
