Donny Osmond Apologizes to Larry King

Larry King stunned guest Marie Osmond last week when he abruptly asked her about her 16-year-old son’s decision to enter rehab, leaving her to stammer, “Uh, how did you know that?”

Soon after, Marie’s famous brother Donny went on the defensive, blasting the talk show king for catching Marie off-guard.

However, Donny is now thanking Larry for making the secret public.

Donny tells the “Today” show that Marie didn’t know the tabloids were about to publish the story.

“In hindsight, Larry King did Marie a favor,” says Donny. “I’m grateful he gave Marie that platform, that opportunity, to speak worldwide about a problem she's going through.”
