Shahid and Kareena- may be refusing to promote together their new film!

Shahid Kapoor and Kareena Kapoor may ruin the chances of their new film as they are refusing to promote it together.

Milenge Milenge co-stars the ex-lovers, who ended a three-year relationship in 2007.

Shooting began in 2004, but the film has been besieged by delays, as well as rumours that the former couple refused to work on its post-production.

It is reportedly based on the romance Serendipity.

Producer Boney Kapoor told the Hindustan Times: "Shahid shot for the video, but I am yet to get a nod from Kareena. I think she is busy shooting for Golmaal 3. I am waiting for her to get free.

"The film will definitely release on June 25. It'd be nice if they promote the film together. But I don’t have a final call on it. They have agreed to promote it, but not together, yet."
