Actress Cheryl Hines is preparing to marry her fiance Robert Kennedy, Jr. on 2 August (14), according to a U.S. report.

The Curb Your Enthusiasm star, who became engaged to the attorney in April (14), is plotting a large wedding at the Kennedy family's home in Hyannis Port, Massachusetts and it will reportedly take place across the weekend of 2-3 August (14).

Editors at the New York Daily News report the couple will enjoy two days of festivities with around 600 guests.

A source tells the newspaper, "Bobby wanted a small wedding, but he has a big family of at least 150 people and she has a huge family in California, so they have invited 600 people - and that's small for the Kennedys."
