The 'Bhoothnath Returns' stars had visited the sets of the show and the episode was aired last weekend.
"Namaskar Amitabh Bachchanji, Boman Iraniji, Kapil Sharma. Aisa comedy show maine aaj tak nahi dekha. Aap sab ko badhaai (I have never seen a comedy show like this. Congratulations to all)," the 84-year-old posted on Twitter on Sunday.
She had earlier met Kapil, host and producer of the show, at her recording studio.
