It was fun and masti like never before when actor Ayushmann Khurrana and his charming Nautanki Saala co-star Kunaal Roy Kapur were on the sets of Zee TV's kids reality show India's Best Dramebaaz to promote their upcoming film.

Kids, judges and hosts alike couldn't get enough of the awesome twosome on the show.

The li'l kid contestants on the show were so captivated by their 'Ayushmann bhaiya', that they made sure that he did something special with each of them after their acts.

When Ayushmann and Kunaal took on Anjali's challenge of singing the 'Twinkle twinkle' nursery rhyme with a typical Punjabi tadka and soulful opera style respectively, the entire studio audience were on their feet, demanding an encore performance.

On Kunaal's insistence, Praneet taught both the stars how to enact his trademark 'chota sa nanha sa bacha' complete with the Shakti Kapoor accent and pelvic thrust that made him a household name during the auditions.

The duo also shook a leg to the catchy 'dhak dhak karne laga' from their film with host Rithvik Dhanjani who was made to dress in a sari and bindi courtesy Praneet's mum who expressed a strong desire to see Rithvik also dressed like a woman.

Ayushmann floored judge Sonali Bendre with his charming rendition of Raj Kapoor's iconic 'Pyaar Hua' under the umbrella.

With his soulful voice, it was a given that the cast and crew of India's Best Dramebaaz wouldn't let Ayushmann leave before he sang a song for them.

The actor of course obliged with a catchy mashup of 'Paani Da' and 'Mera Mann Kehna Laga'.
