JUST months after the tragic suicide of his wife, ROBERT F. KENNEDY Jr. plans to wed GF CHERYL HINES, sources say.

The coldhearted cad fractured his famous family when he flaunted his romance with the former “Curb Your Enthusiasm” star during his estranged wife Mary’s sad last days.

As The ENQUIRER reported, he also dug up Mary’s body seven weeks after her burial and banished it to a remote area of the cemetery – because she was too close to the graves of his beloved aunt and uncle, Eunice and Sargent Shriver!

“But this time Bobby has REALLY outdone himself in the bad taste department,” a family insider told The ENQUIRER.

“Now he’s running around telling everyone he and Cheryl are getting hitched in the spring. It will be on the East Coast, probably at the Kennedy com­pound in Hyannis Port. The family’s appalled.

“Four of his kids just lost their mother and now their father’s crowing about having a big blowout wedding, which, for the record, will be his third.”

As The ENQUIRER reported, 46-year-old Cheryl was devas­tated and guilt-ridden over the shocking death of her beau’s wife, and she considered calling off their romance.

“Rather than tearing them apart, their shared grief ended up bringing them closer together,” explained another source.

Kennedy, 58, has been dating Cheryl – now starring in the ABC sitcom “Suburgatory” – since late 2010, and the two were spotted taking a romantic stroll at the family’s oceanfront compound on Aug. 5.

“They’re more in love than ever,” said the Kennedy family insider. “Bobby can’t wait to tie the knot, but a lot of the family is disgusted with him!”
