The superstar made the confession on Zee TV's "DID Super Moms" while promoting his film "Chennai Express".
On the show, he was blown away by flexibility and talent of contestants Cecille and Shivangi, who performed a Mallakhamb act which had them executing backward flips on a five-foot wide wooden block.
On hearing Shah Rukh's comments for the contestants, the show's judge Farah, who had choreographed "Jiya jale" for the movie "Dil Se..." reminisced how she had tried to get Shah Rukh to do a few Mallakhamb steps for the song.
"On the shoot day, Shah Rukh vanished from the sets and was nowhere to be seen. I had specially ordered a white lungi and wanted him to be bare chested while shooting the song," she recalled.
To that Shah Rukh came up with a quick rejoinder.
"Don't worry Farah, for your next movie, I promise I will do a Mallakhamb. If you dress me in white for it, I will also be your Mandakini and give you four days to shoot the song as well," said the superstar with a naughty grin.
Mandakini, a former Bollywood actress, had caused a stir with her daring act of bathing under a waterfall, wearing a flimsy white sari in 1985 film "Ram Teri Ganga Maili".
