Superstar DJ Mark Ronson has laughed off rumours of a romance with English singer Amy Winehouse, dubbing them "hysterical".
British newspapers claimed the two were dating after working together on Winehouse's latest album Back To Black.
But the music producer, who has previously worked with Robbie Williams and Christina Aguilera, told British magazine Star: "It's the most ridiculous thing I've ever heard.
"She calls me the big sister she never had! Amy makes a really nice meatball dinner. She's good at making Jewish mother food."
