Karan Johar did a belly dance while promoting his film We Are Family on India's Got Talent on Monday. KJo, Kareena Kapoor and Arjun Rampal were guest judges on the show.

A Bhangra School of Dance from Delhi performed a belly-dancing act, and later some of the girls went to the star guests and pulled them on to the stage to join them in a hippy-hippy shake-shake.

Karan was reluctant, but after judge Kirron Kher egged him on, he went on stage and sportingly did a little jig. When Arjun asked the audience who was a better belly dancer, the crowds screamed "Karan!".

Prior to the show, KJo dropped in to meet Farah Khan on the sets of Tees Maar Khan where Katrina was shooting for a belly-dancing song. And everyone teased the director of taking secret lessons from the actress, who will be seen in his next production Dostana 2."

Karan says, "I just did a few steps. It's easier for me to do a belly dance as I have a belly but I fool everyone with my black attire so people believe that I don't. My motto is: when in doubt, wear black! I didn't do any major number, just moved my hips for a few seconds but it was fun! I am willing to do anything in the name of promotion for my films."

But while Karan impressed the audience with his belly-dancing act he was himself impressed by one particular guy. "His name was Pradeep and he did a brilliant fusion piece -- a rap number in Marathi, English and Hindi. He was confident and assured and seemed to be the crowd favourite."
