The two actors, who are busy promoting their soon-to-release film "Mere Brother Ki Dulhan", will be seen on megastar Amitabh Bachchan-hosted show Thursday.
Imran danced on "Sheila ki jawani..." and also copied her famous steps, and gets an applause and a pat on the back from original 'Sheila', Katrina.
According to a source from the sets, both the actors were quite enthusiastic. Katrina, who has learnt how to play a guitar for the film, even strummed the instrument for Big B, while Imran sang for him.
The 68-year-old wished both Imran and Katrina all the best for their film, which releases Friday. The movie also features Pakistani actor-singer Ali Zafar.
