Scarlett JohanssonStella McCartney has said she’s adamant about designing Scarlett Johansson’s wedding dress - whether the Lost in Translation star wants her to or not.

Speaking at Monday’s Costume Institute Gala in New York, Stella told People magazine: “I’m definitely doing her wedding dress. She doesn’t know it yet.”

She jokingly added that she already had ideas in mind even though the actress’ engagement to Ryan Reynolds was only announced that afternoon: “You know, some kind of dodgy, black thing. Latex! Latex for Scarlett!”

Stella designed Madonna’s wedding dress when the singer married Guy Ritchie in 2000.
