Prabhu Deva made the startling revelation about Akshay on UTV Stars' "The Chosen One".
He had to assign and judge a task for young contestants on the show, and in the meantime, he narrated interesting anecdotes straight out of the sets of "Rowdy Rathore".
That's when he told the contestants about Akshay's apprehensions about dance.
He said the actor remains stress free as long as he doesn't have to shake a leg. But when asked to groove, he used to hardly talk.
In fact, Prabhu Deva said he had to indulge in pep talks with Akshay before shooting any dance sequence.
The filmmaker, an accomplished dancer himself, said that Akshay used to say: "Everything else is fine but when the song starts and I have to shake myself, I go blank! It really scares and stresses me!"
