Like Marilyn Monroe before them, Hollywood's ladies just can't keep their hands off the Kennedys. One week after photos of Taylor Swift and Conor Kennedy surfaced, fueling rumors that the "Love Story" singer and the grandson of the late Robert F. Kennedy are dating, "Curb Your Enthusiasm" actress Cheryl Hines was snapped aboard a boat with her Kennedy of choice, Robert F. Kennedy Jr.

In addition to boating off the coast of the family's Hyannis Port, Mass. compound, Hines, 46, and RFK Jr., 58, spent time on the beach with her daughter. They were joined by Maria Shriver and more members of the Kennedy clan.

Hines and RFK Jr. made their relationship public shortly after his ex-wife, Mary Kennedy, committed suicide in May. Hines was previously married to businessman Paul Young.
