Dolly Parton had a bit of advice for Kelly Clarkson and she and her children grieve the loss of Brandon Blackstock.

Clarkson has yet to speak out about Blackstock’s death — but she’s said to be “devastated” for her kids River, 11, and Remington, 9, over the tragedy. “When she found out that he was sick, she remained protective of him for their sake,” an insider told People on Friday.
