The Titanic star, who once put family ahead of her career, has announced she's parting ways with film director husband, Jim Threapleton, after three years of marriage and one heavenly creature--baby Mia, who was born just late last year.
According to Winslet's reps, the split was on good terms.
"No other parties are involved in this amicable and respectful separation," reads a statement from Winslet rep Robert Garlock. "Their daughter Mia will remain the first priority for both of them."
Her turn as Rose in Titanic opposite Leonardo DiCaprio made her an international star and romantic icon for teen girls worldwide, but things weren't always so rosy on the homefront for the 25-year-old British actress.
"Having a baby has strengthened the relationship, although there are highs and lows and at times it's tough. I know we're very lucky," Winslet tells InStyle in an interview for its September issue.
Winslet met Threapleton, a 27-year-old assistant director, on the set of the movie Hideous Kinky in 1997. The couple swapped vows a year later in November 1998 in a quiet ceremony in her family's local church in her hometown of Reading in southern England.
Winslet, by then one of the most coveted actresses in Hollywood, decided to take time off to have Mia and spend more time with her new family. After the birth of their daughter, Winslet and Threapleton purchased a $1.17 million riverside mansion in Britain.
The actress has recently resumed a busy schedule. She most recently starred opposite Geoffrey Rush in last year's Quills and next hits the big screen later this year in director Michael Apted's World War II spy thriller Enigma.
