A grandson of billionaire energy mogul J. Paul Getty was found dead Tuesday inside his Los Angeles home with a rectal injury, according to reports.

Police responding to a 911 call of cardiac arrest at a Hollywood Hills home found Andrew Getty, 47, deceased in his bathroom at about 2:18 p.m., officials said.

Getty suffered a traumatic injury near his rectum that caused significant bleeding, TMZ reported.

He was found naked from the waist down and had suffered some kind of blunt-force trauma, law enforcement sources told The Los Angeles Times.

Despite those odd circumstances, investigators said they don’t believe Getty was the victim of foul play.

“At first glance, it does not appear to be a criminal type of act. But that could change,” LAPD Cmdr. Andrew Smith said.

The oil heir had been feeling under the weather in recent days and had a doctor’s appointment set for Wednesday, a coroner’s official said.

“The tentative information that we do have is that he was not feeling good for the last couple months,” Los Angeles County Coroner’s Assistant Chief Ed Winter said, “and he supposedly had an appointment (on Wednesday) with a personal physician.”

Investigators seized prescription meds from Getty’s home.

“He had some medication that we recovered and don’t know if he had taken the medication or what his medical history is, we do have a doctor’s name that we’re also going to follow up,” Winter said.

Getty’s ex-girlfriend Lanessa De Jonge found the body and called 911, KTLA in Los Angeles reported. She’s cooperating with cops.

The couple had a troubled history, including 31 LAPD visits to Getty’s home for domestic disturbance and drug use, TMZ reported.

Getty had gone to court and asked for a restraining order against De Jonge, according to KTLA. The case had been scheduled to go to court next week.

This isn’t the first brush with tragedy for the family.

In 1973, a 16-year-old grandson of J. Paul Getty was kidnapped.

The kidnappers sent the teen’s severed ear to his family, who paid $2.8 million for his release.

Getty’s dad, Gordon Getty, is the world’s 894th-richest man with a fortune worth $2.1 billion, according to Forbes magazine.
