KJo party with Alia, Varun, Sidharth

Who would be happier than Karan Johar today? You actually feel happy when your creation beams in the light of success. And his students Alia Bhatt, Varun Dhawan and Sidharth Malhotra have actually made him feel proud. While Sidharth's Ek Villan has reached the 100 crore club, Varun and Alia's Humpty Sharma Ki Dulhania has got a brilliant opening. This is going to be Alia Bhatt's fourth hit in a row. And this was a good enough reason to celebrate. The four had a party together where they literally let their hair down. Karan is one proud mentor who is enjoying the success of his kids to the hilt.
