The young generation seemed to be the crux of filmmaker Karan Johar's house party, the star attraction being rumored couple Ranbir Kapoor and Katrina Kaif.

Filmmaker Karan Johar's party on Sunday witnessed Kareena Kapoor in a traditional attire of a silk mustard salwaar kameez.. However, Katrina Kaif kept it chick in a short floral dress with loose hair. The diva was all smiles as she ventured out and was closely followed by boyfriend Ranbir. The actor gave a quick hug to cousin Kareena, before following Katina out.

Sidhharth Malhotra of "Student of the Year" fame looked every bit casual in a check shirt as he waited for his car. Aditya Roy Kapoor was in black as he flaunted a raw look with his partial bald haircut.

With Ranbir Kapoor around, good friend and director Ayan Mukherjee was also present. The hit duo are said to be close to Karan Johar, having worked in films like "Yeh Jawani Hain Deewani" and "Wake Up Sid" under the filmmaker's banner.

While Karan appeared to keep a low profile and wasn't seen around, Ayan was spotted casually smoking a cigarette, as he enjoyed the company. Interestingly, Katrina was also seen hugging Kareena, dispelling rumours of the cold vibes between the top actresses.
