Bollywood superstar Shah Rukh Khan says his assistants on his movie sets jokingly call him Michael Jackson because of his love for dancing.

The 48-year-old star says he follows advice of director and close friend Farah Khan and dances from his heart.

"Whenever I dance I am always happy. Farah can vouch for that. I never hold myself back. There are assistants on the set and they jokingly refer to me as Michael Jackson. As they feel that inside my shoes my toes are dancing.

"I remember during 'Raju Ban Gaya Gentleman' Farah told me that don't worry and be happy when you are dancing. For last 20 years this advice has really helped me," said Shah Rukh, who will be seen judging a dance reality show 'Dil Se Naachein Indiawale' with Farah Khan on Zee.

The 'Chennai Express' star, however, said he is not a very good judge as he marks people on the basis of their passion for dance rather than on the technicalities in their performance.

I am a very weak hearted judge. I think if someone can just come to stage with lots of passion and dance and win people's hearts, I will give full marks to them without seeing the technicality and the complexity of the dance. "I remember once I went to judge Miss India and Waheeda Rehmanji was also there as a judge. I asked her to show her numbers because I liked all of them. So I try to avoid judging shows," said the actor, who will be seen taking part in a dance competition in his upcoming musical heist 'Happy New Year', directed by Farah.
