Another sibling for Winslet's daughter Mia

Kate Winslet's daughter Mia will soon be a big sister to a half-sibling - the 'Titanic' star's ex-husband Jim Threapleton is expecting a child with his second wife.

Winslet, 33, remains on good terms with filmmaker Threapleton, who she divorced in 2001, and even spends time with him and their eight-year-old, Mia, as well as her new husband, director Sam Mendes, and their four-year-old son Joe.
