Sylvester Stallone continues to cope with the unnatural act of outliving his son Sage, who was found dead last week at the age of 36. Sadly, there are several other celebrity parents who can relate to the Stallone family's loss.
John Travolta and Kelly Preston's son, Jett, died in 2009 while the family was on vacation in the Bahamas. The 16-year-old was determined to have died from a seizure.
Three years after the tragedy, Preston tearfully described her son as "the most beautiful being" during an interview with Amanda de Cadenet.
Similarly, Marie Osmond had an emotional interview with Oprah Winfrey following the death of her son, Michael, who committed suicide at the age of 18.
"I said, 'Mike, I'm going to be there Monday, and it's going to be okay,'" Marie said, describing her last phone conversation with her son the day before he died. "But depression doesn't wait till Monday."
Anna Nicole Smith never fully recovered from the death of her 20-year-old son, Daniel, in 2006, as she passed away the following year.
Eric Clapton's son was just a toddler when he suffered a fatal fall in 1991, which inspired Clapton's song Tears in Heaven.
Kirk Douglas, 95, and Barbara Eden, 77, each lost children to drugs. Douglas' son, Eric, was found dead in his New York apartment at 46, while Eden's son, Matthew, overdosed on heroin at 35.
Carol Burnett's daughter, Carrie, lost a battle with cancer 10 years ago, and she admitted to us that you never "get over" the death of a child.
"You learn to cope," said Carol, who went on to add, "I would rather have had her with me than to never have known her."
Bill Cosby tragically lost his son Ennis at the hands of a gunman who killed the 27-year-old in Los Angeles 15 years ago. The comedian and actor later revealed to CBS News what he said at his son's funeral: "Praise to God for allowing us to know him."
