Georgina Chapman – the co-founder of luxe fashion label Marchesa – is pregnant with her first baby.

According to The New York Post, the London-born brunette is expecting with her film producer husband, Miramax boss Harvey Weinstein.

The new arrival will be the movie mogul's fourth child – he has three daughters; Lily, Emma and Ruthie, from his first marriage to Eve Chilton - and is thought to be due in September.

Thrilled Georgina, 33, has reportedly confirmed the news, recently telling the Daily Front Row: "We're so excited!"

The couple - pictured together in February - met back in 2004, and married three years later in Connecticut.
