/> Apparently Sonam Kapoor the leading lady of I Hate Luv Storys (IHLS) was supposed to fly down to Mumbai for the celebration party on Saturday. But she did not eventually show up because of the tight schedule in Edinburgh for Mausam.

Says a source close to the actress, "Too much of the Mausam schedule had already been disturbed because Sonam had to take a break to return to Mumbai to promote IHLS. There was no way she could return for even a day."

Direcror Punit Malhotra was seen solo at the party but hardly looking lost.

"We had a mad evening. It was super-entertaining. I got everyone drunk, " said Punit the day after the party. Everyone from Sammir Dattani to Karan Johar was hung-over the next morning, Puneet made sure of that.

Surprisingly Imran Khan too came solo to the party. According to Punit his girlfriend Avantika was traveling. But another source revealed that Avantika decided to have a girls' night out with her friends while Imran whooped it up with the IHLS gang.

Punit personally went around chasing the guests down and drowing shots down their throats.

Yes, Aamir Khan did show up, solo, for the I Hate Luv Storys celebration bash. But someone very close to Karan Johar suggests not to read too much into this so-called new friendship.

"Aamir invited Karan to his Peepli Live music release. Karan invited him back for his IHLS party. That's it. To conclude that they are working together in a film is not just pointless it's also unnecessary."
