"Later, even Bappi-da came and sat for sometime," the spokesperson added.
The yesteryears star was admitted to the hospital Monday. His condition remains critical.
"Joy is running high fever, he is still unconscious and his overall condition is still critical. Six doctors are working on his health," said the spokesperson.
