Hollywood celebrities sent Larry King their well-wishes and prayers for his recovery following news that he is battling COVID-19 at Cedars Sinai Medical Center in Los Angeles.

A source close to King's family confirmed to CNN that the talk show host was admitted to the hospital over a week ago. His sons could not be there for him even just to see him due to the health and safety protocols at the hospital.

The confirmation corroborates an earlier report from Showbiz 411 about the 87-year-old's COVID-19 diagnosis. His sons Chance and Cannon and his wife of 23 years, Shawn King, are not allowed to visit him. But they are said to be in constant communication with the hospital and doctors who are monitoring his condition.

"Star Trek" alum George Takei also wished King a "speedy recovery" and singer Richard Marx wrote, "Rooting for you #LarryKing."

"Get well Larry, I'm pulling for The King," Chief International Anchor for CNN Christiane Amanpour tweeted.

King can be considered high-risk for COVID-19 not only because of his age but due to his prior health issues. He had several heart attacks and had quintuple bypass surgery in 1987. He also underwent surgery in 2017 to treat lung cancer and went through another medical procedure in 2019 for his angina. He also has Type 2 diabetes.
