'I've a weakness for Karan Johar,' confesses Kareena Kapoor as she gets ready to face the camera under the superstar-director's stewardship after 'Kabhi Khushi Kabhie Gham'. This time, however, it's only for an ad for a popular brand of paint. 'But how does it matter if it's three hours or three minutes? I'm as excited about this ad as I was when I did 'Kabhi Khushi Kabhie Gham' with Karan years ago.' A maelstrom of memories flood Kareena. 'I was treated like a princess on the sets of K3G,' she says. Speaking about boyfriend Shahid Kapoor, she says: 'Things couldn't get better for both of us. Shahid had 'Vivah' in 2006. 2007 starts for me with one of my favourite directors Karan and ends with another favourite, Mani Ratnam.' Why the paint ad? 'Because I like colours. I associate colours with youth and I feel I connect best with young audiences. Karan will be able to bring out the most vibrant side to my personality in that one short film. I'm as excited about it as I'd be about any feature film. I've realised Karan and I are inseparable.' A feature film next with Karan? 'A-ha, wait and watch. There're plenty of surprises from me in 2007,' Kareena signs off.
