The first look of Kareena Kapoor and Imran Khan starrer "Ek Main Aur Ekk Tu" is out and producer Karan Johar has clarified that his forthcoming romantic comedy has nothing to do with Hollywood movie "What Happens in Vegas".

Slated to release next February, "Ek Main Aur Ekk Tu" has been directed by newcomer Shakun Batra.

There were reports that the film's story is on the lines of Cameron Diaz and Ashton Kutcher starrer "What Happens in Vegas", but Karan said: "The fact that they get married in Vegas is only an aspect of the movie and not the entire movie

. When you see the film in February, the fact will unveil itself that there is not a single note or point of similarity between the two films. They are totally different movies."

The 39-year-old producer-director, who has not wielded the megaphone since "My Name Is Khan", says he will return to direction with "Student Of The Year", which will be co-produced by Red Chillies Entertainment.

"Ek Main Aur Ekk Tu" first look was unveiled Wednesday and lead pair Kareena-Imran, who are working together for the first time, were also present.

Sharing her experience Kareena said that working with Imran was like a breath of fresh air.

"Imran has brought a lot of freshness and I think the chemistry is pretty sizzling and crackling as you can see in the promos and I actually really really enjoyed working with Imran and he is actually a very very sweet guy. Imran in not funny but very very sweet," the 31-year-old actress said.

A self-confessed Kareena fan, Imran talked about how desperately he wanted to work with her.

"We could only see one person in this role, even though she didn't have the time when we were originally planning the film. We said we would wait for her because we were so sure that only she could do this role.

We felt it is a very performance-oriented role and she would be the best person to bring that one to life," said Imran who was last seen in "Mere Brother Ki Dulhan".
