"The party was meant to be with people I love. I can't help it if I love famous people so much. They all turned up, looking great. I always wanted this," Johar, who turned 40 May 25, said.
From Shah Rukh Khan, Priyanka Chopra and Bipasha Basu to Aamir Khan, Vidya Balan and Jaya Bachchan - Bollywood's who's who had tip-toed into the bash at a suburban hotel.
"At the lack of having a wedding opportunity, where everybody comes dressed and you want all those photographs in an album somewhere, I just thought I would make the 40th birthday an excuse to call all the people I have interacted with in my 15-year career in the industry," Johar said.
"I always wanted them to be well-dressed and well-turned-out, so I wanted a red carpet, black tie bash, and that's what I did. It's been my biggest hit so far - my party," he added.
As a director, Johar is credited with films like 'Kuch Kuch Hota Hai', 'Kabhi Khushi Kabhie Gham', 'Kabhi Alvida Naa Kehna' and 'My Name Is Khan'. Now he is busy working on his next 'Student Of The Year', and has also signed up to judge dance reality show 'Jhalak Dikhhla Jaa', going on air on Saturday.
