We like to imagine that if we were famous and wealthy our lives would be perfect, but that's just not true.
Even celebrities live through personal tragedies, from breakups and setbacks to the worst tragedy of all, losing a child. You'll remember some of these cases because they were very public, but others were kept private for years, or even decades.
If you still think that movie stars and musicians have perfect lives, read this list of 17 big stars whose children died much too young.
1. Loretta Lynn
This country star's had a lot of tragedy in her long life. Her father died before she ever became famous, and she's outlived two of her children. Her son Jack Benny Lynn died trying to ford a river on a horse, and her daughter Betty Sue passed away in 2013 from emphysema.
2. Mary Tyler Moore
This comedienne's son Richard shot himself accidentally at age 24. There had been a rash of home invasions in his neighborhood, so he had a gun to protect himself. One day he was playing with it and it fired by accident.
3. Piece Brosnan
This Bond actor has had his share of sadness. His wife, Australian actress Cassandra Harris, died of ovarian cancer in 1991. Years later, the couple's daughter Charlotte would pass away after a fight with the same disease.
4. Mia Farrow
Between her own children and the 10 she's adopted, this star of Hannah and Her Sisters has raised 14 kids, but some have sadly passed away. Three of her adopted children have died: son Tam died at age 19 from a heart condition, her daughter Lark died from unrevealed causes at age 35, and her son Thaddeus committed suicide when he was 27.
5. Marie Osmond
Marie's son Michael was very troubled, and eventually took his own life. In his suicide note, he explained that he always had trouble connecting with people his own age.
6. Keanu Reeves
People like to joke about how sad this The Matrix star looks sometimes, but he has every right to be sad because his life has been pretty tough. His daughter with his girlfriend Jennifer Syme was stillborn, and Syme died in a car crash just a few years later.
7. Joe Biden
The former vice president has been married twice. His first wife and their daughter Naomi were killed in a car crash that also sent his sons Beau and Hunter to the hospital. They both pulled through, but nearly 40 years later Beau died of brain cancer. Biden kept his illness a secret, but slowly lightened his schedule so he could spend more time with Beau before he passed.
8. Sylvester Stallone
You may remember Stallone's son Sage from Rocky 5, where he played the famous boxer's son, but he had a successful career of his own. Sage was working as a director and producer when he died from heart disease in 2012.
9. Paul Newman
Scott Newman had roles in a handful of Hollywood films like The Towering Inferno, but his career was tragically cut short when he died of a drug overdose at age 28. His father built the Scott Newman Center, a drug rehab and education building, dedicated to his life.
