The English actor, who is best known for the films About a Boy, Four Weddings and a Funeral and Notting Hill, filed a defamation suit against Associated Newspapers, the parent company of both the Daily Mail and Mail on Sunday.
The papers had published stories that Grant’s relationship with Jemima Khan ended because Grant was flirting with another woman, and acting strangely concerning the marriage of his former girlfriend, Liz Hurley.
The actor claimed that the stories were, "almost entirely fictional articles about my private life".
The two papers have issued an apology to Grant and are retracting the stories. Grant will donate the money to the Marie Curie Cancer Care charity.
