That was one big, lavish birthday party. Those who were there believe they had not seen such an extravagant birthday bash in a while at which the who’s who of the Indian film industry were spotted. Yes readers, Bollywood macho director Karan Johar, aka K-Jo turned 40 on May 25 (almost over the hill). Last week he hosted a grand event at the swankiest of Mumbai hotels and some of those who brought presents for him were Shahrukh Khan, Gauri Khan, Mr and Mrs Yash Chopra, Vidya Balan and her boyfriend Sidharth Kapoor, Hrithik Roshan and his wife, Preity Zinta, Bipasha Basu, Ritesh Deshmukh and his wife Genelia D’ Souza, Ali Zafar and Sonakshi Sinha. Imagine the stellar guest list. However, a certain Ms Piggy Chops (read: Priyanka Chopra) was conspicuously absent. Why? She wasn’t invited. K-Jo and Piggy Chops: catfight?
