Bollywood' lucky mascot Katrina Kaif may soon star in musician-actor Ali Zafar' music video, thanks to a bet that took place on the sets of their last film 'Mere Brother Ki Dulhan'.

The story goes that Katrina had promised co-star Ali that she'd star in his next music video if the film made a box office milestone....t day isn't too far considering that 'Mere Brother Ki Dulhan' has crossed the 50 crore mark.

Says Ali, "I have a written consent from Katrina, along with a video recording on my phone, but I won't pressurize her. If she wants, I'll compose a song for her and we'll record it next time we're in Mumbai, probably in November for the MBKD success bash."

For Katrina Kaif, the singer-actor is willing to experiment with the song that promises to show fans a new side of her. "She's a delicate soul. If she appears in my video, you’ll see a side to Katrina you've never seen before," adds Ali.
