She began, "This one hurts. It’s really hard to face this reality about an old friend. There was so much warmth in the McGuire family, and I always felt so cared for by my on-screen parents.”

“I’ll be forever grateful for that. I’m deeply sad to learn Bobby was suffering. My heart aches for him , his family, and everyone who loved him,” the Disney star concluded with a broken heart emoji.

It is pertinent to mention that the news of Carradine’s passing was shared by his brother, Keith Carradine.
