CHIP OFF THE OLD BLOCK: Guests at the Carven show in Paris included the local equivalent of Hollywood royalty: Morgane Polanski, the daughter of director Roman Polanski and actress Emmanuelle Seigner.


Mother and daughter are among the faces of the Marc Jacobs spring campaign, and the younger Polanski is showing a keen interest in fashion, with front-row appearances at Miu Miu and Roksanda under her belt.


“As I live in London, I love Sixties-style clothes — high-waisted skirts, high-waisted pants or jeans with shirts,” she said.


Polanski has been donning heavier garments in her role as Princess Gisla in the History channel series “Vikings.” Season four, which started screening last month, will show her feelings soften toward her husband, the Viking warrior Rollo.


“Let’s say only idiots don’t change their mind. He’s going to try to prove his worth,” she said. “My character really has a very, very beautiful journey.”
