The 79-year-old actor has claimed the former 'Two and a Half Men' star is paying the price for his party-loving lifestyle and he doesn't feel sorry for him in any way, saying he "deserves" to have contracted the virus.
Burt - whose career was beset by HIV rumours in the 80s - was asked if he felt sorry for Charlie, and he said: "For Charlie, no, he deserves it. He misbehaved badly. Very badly.
"But you know when you're that age, it's tough. All those things are coming at you and it's difficult."
Burt said he's a close friend of Charlie's father, American actor Martin Sheen, and he is sympathetic towards his situation.
Speaking while recording an interview on ITV's 'Loose Women', the 'Boogie Nights' actor said: "He's handled it badly I think. His father is a very, very decent man and a dear friend of mine.
"I feel bad for him, but Charlie, I don't feel bad for him. He's getting what he deserves. If you're going to misbehave like that, they're going to get you."
A member of the show's audience subsequently told The Sun newspaper: "The audience were shocked - as were [TV hosts] Ruth and Coleen - and there was an extremely awkward silence. Of course, HIV is something that no one deserves."
