KJo threw an impromptu bash to celebrate the success of Parineeti Chopra-Sidharth Malhotra starrer!

Karan Johar is surely on the seventh heaven as his recently released film, Hasee Toh Phasee, which stars Sidharth Malhotra and Parineeti Chopra got a good opening at the box-office.

The talented filmmaker made sure to celebrate the success of the film by throwing a bash for his close friends at his Bandra residence recently.

The bash was attended by Ranbir Kapoor and Ayan Mukherji – who happen to be KJo’s real close friends – along with Arjun Kapoor and Aarti Shetty. According to a bitchy birdie, Ranbir’s alleged girlfriend, Katrina Kaif was also invited for the party, but she couldn’t make it as she is busy shooting for Bang Bang in Shimla. Considering all is not well between the two lovebirds since quite a few days, we wonder if shooting in Shimla was the real reason or was she not interested in facing the Kapoor lad? Also we wonder why was Ranboo hiding his face with the help of an iPad box. Did he not intend to reveal his look from his upcoming film, Bombay Velvet or was he ashamed of something?

Anyway, we congratulate everyone associated with Hasee Toh Phasee for the phenomenal success of the film. Kudos!
