Natalie Cole’s son Robert Yancy was found dead in his San Fernando Valley, Calif., apartment on Monday night.
He was 39 and Cole’s only child.
The death was attributed to natural causes.
Natalie’s twin sisters, Casey and Timolin, told Page Six: “We are saddened, completely heart broken beyond words at the death of our nephew. It’s an inexplicable loss to our family, especially after losing Natalie.”
Yancy was the grandson of the legendary Nat King Cole.
Natalie passed away in 2015 from congestive heart failure.
Her sisters continue to preserve their family’s legacy through their Nat King Cole Generation Hope foundation. “We want the world to know we’re going to do everything we can to keep our father, our sister and now Robbie’s legacy and name alive. He’s up in heaven with royalty,” Timolin said.
