Shahid Kapoor who's considered one of the best dancers in Bollywood is now trying out a new dance form called Krumping.

He'll be doing this exotic dance for 'Yahoo', to be directed by Ken Ghosh and it's a musical flick based on dance.

But though he's a great dancer he was extremely nervous before learning this dance form.

It's kind of an urban street-dance, now a part of popular hip-hop dance culture. It requires highly energetic moves which includes great movement of chest and arms. American choreographer James Martin Kudelka, better known as Marty Kudelk is choreographing Shahid's dances in the film.

Interestingly he's also the personal choreographer of pop star Justin Timberlake.

Shahid has said, "I remember the first day of rehearsals with Justin's choreographer Marty. Suddenly I started getting sweaty hands and became nervous. I was feeling that it's very nice to see the videos of people and say that we too can dance like them. But when you actually get down to do that, it does make you feel a little nervous. "

After 'Ishq Vishk' and Fida this is his third film with Ken Ghosh. The movie has Jiah Khan as well.
