Winslet secretly exchanged vows with boyfriend Ned Rocknroll in New York earlier this month, and was reportedly given away by her Titanic co-star Leonardo DiCaprio.
Her representative has confirmed the happy news, telling Eonline.com the private nuptials were "attended by her two children and very few friends and family."
Winslet has been dating billionaire businessman Richard Branson's nephew, birth name Abel Smith, for just over a year. They quietly became engaged over the summer.
The 34-year-old was previously married to British socialite Eliza Cowdray, while Winslet, 37, has been married to Jim Threapleton and moviemaker Sam Mendes. The actress has children from both marriages.
The newlyweds reportedly bought a home together in West Sussex, England in September.
