The bash was attended by the likes of Ranbir Kapoor, Ayan Mukerji, Arjun Kapoor and Aarti Shetty.
An onlookers says, "Ranbir walked in a little late and was not his jovial self. Hiding his face behind his iPad, he immediately rushed inside the apartment. He was sporting a cap and it looked like he didn't want to give away his new look for the upcoming film, 'Bombay Velvet'."
Sources say that Karaj Johar threw the party to celebrate his film 'Hasee Toh Phasee' getting a good opening. "Karan called his friends over just like that. But unlike Kiran Rao's party, this bash was not attended by Katrina Kaif, who is currently shooting for the film 'Bang Bang' in Shimla," says the source.
