Seeing the bonding between telly actresses Drashti Dhami and Sanaya Irani on the sets of a dance reality show, judge Karan Johar quipped that in Bollywood no two actresses can be friends

He asked co-judge Madhuri Dixit which actress was her buddy. Mads flashed her pearlies and said her lips are sealed. Hmmm...

KJo knows better being a filmmaker about cat claws and rivalries.
