Recently released romantic comedy 'I Hate Luv Storys' has garnered around Rs 21.5 crore in the domestic zone during the first three days of its release and actor Imran Khan said that he is happy by the 'grand opening', the film has got.

The actore said, "I feel honestly very surprised with the numbers. I had told (director) Punit Malhotra that it's a very good film and I was quite confident with the way it was promoted, but I didn't expect such an opening."

"I Hate Luv Storys", which also stars Sonam Kapoor, is a flick in which Imran plays a bit of a womanizer.

When asked if he thought it was intelligent to release the film after "Kites" and "Raavan", he answered, "I think everything went in our favour. There are the things you can't plan for and everything happened by good fortune."

According to reports, the actor has signed up a movie with producer-director Karan Johar.

It was also said that he would be romancing Kareena Kapoor in the flick.

"See, I have signed another film with Karan, but until he announces it I can't talk anything about it," Imran said.

Imran is also finishing up director Kunal Kohli's "Break Ke Baad", in which he will be seen romancing Deepika Padukone.

Speculation was also rife that Imran may tie the knot with his girlfriend Avantika Malik in January 2011, but he denied it, saying that he would be shooting during that period. (With Inputs from Agencies)
