Kareena Kapoor and Imran Khan are bonding big time with their better halves in tow

Thanks to their latest film together, Ek Main Aur Ek Tu, co-stars Imran Khan and Kareena Kapoor have become fast friends. And that's not all. Their respective better halves are also now friends.

Interestingly, Imran and Kareena didn't exactly hit it off at the start of their rom-com, produced by Karan Johar. Says our source, "Initially, Imran was reserved and a bit wary as he didn't know Kareena well.

Even though she's teamed up with his uncle Aamir Khan in 3 Idiots and has signed Talaash opposite him, it took a while before Imran and she became friends, " says our source. In fact, they even kept meeting each other, off the sets.

The source adds, "If they were going for an event, they'd hang out together. Unlike Imran, Kareena became instantly friends with Avantika. When Saif would be around, he also joined them."

They even went dining together recently. The source points out, "When the last schedule of Ek Main Aur Ek Tu was wrapped up, the two actors decided to go out, along with their partners. They visited a fine dining restaurant in Bandra, that was suggested by Bebo."

Kareena has always been vocal about her liking for the younger Khan. "I like working with Imran Khan. I have always said that he is a superstar of the next generation. I like his personality, " she had said in an interview earlier this year.
