Choreographer Remo D'Souza has certified filmmaker Karan Johar as a "good dancer" who can do some really "professional spins".

"He is typically Karan Johar, who will first say no, but then (he) picks up really fast. You should see his spins, they are too professional and fantastic," the 39-year-old said here during the shoot of the promo of dance reality show "Jhalak Dikhhla Jaa".

"He keeps saying that he cannot dance, but he is a very good dancer," said Remo.

The upcoming season of the dance reality show will once again see Remo, Karan and Bollywood's dancing diva Madhuri Dixit, on the judges' chair. The trio recently shot together for a promo of the show. They can be seen dancing in it.

Karan admits he could only do it as it was shot in bits.

"Steps were not complicated, so it didn't take much time for me to learn them. We do it in cuts, so it's not such a big problem. But if I had to do the whole set piece together, then it would have been difficult for me," Karan said while shooting for it.

The trio have been judging the dance reality show since 2010 and this will be their third appearance together.

TV actor Gurmeet Choudhary had won the fifth season, which ended in September 2012.
