Just three months after his estranged wife, Mary Richardson Kennedy, committed suicide Robert F. Kennedy Jr. and his girlfriend Cheryl Hines spent a fun filled day in the sun and RadarOnline.com has the photos of the happy couple getting frisky on the beach.
Bobby and Cheryl have been dating for years, and she joined the illustrious family on their famed Hyannis Port, Mass. compound where they played in the water, she in a white bikini bottom and he showing off his athletic body in shorts with a belt that he wore in the water.
Also attending their love fest was Bobby’s cousin Maria Shriver, who rocked a black one piece bathing suit.
Cheryl and Bobby were very affectionate, walking on the sand with their arms around each other after swimming in the ocean.
"It was very tough for Mary to deal with Robert dating someone else," the source says. "And it really didn't help that the new woman is a celebrity. She would see photos of the two of them together and it would drive her nuts. I think, deep down, she had still harbored a belief they would get back together but it had recently become blindingly clear that wasn't to be."
