Rani Mukherjee, who used to be the muse for filmmaker Aditya Chopra, is no longer the director's lucky charm.

Adi, as the filmmaker is fondly called in the industry, held Rani of Black fame in high esteem as his lucky mascot until recently, when it seems the spell of another Bollywood belle has been cast on him. The new arrival in the filmy world of Adi is none other than the charming Katrina Kaif.

A source close to the filmmaker reveals that Adi has developed a liking for Katrina after New York, starring Kat along with Neil Nitin Mukesh and John Abraham, became a blockbuster last year.

The words emanating from the grapevine are that being bitten by the bug that is Katrina's beguiling beauty, Aditya has been spending quality time with her. In addition, the Bollywood beauty has been taking career tips from him as per the reports.

The buzz in the air also reveals that Katrina has walked out of Abbas Mustan's The Italian Job because Adi thought that this is the high noon of her career and she should not do insignificant roles.

The source also informs that Kat is going to do three films under the banner of the Chopras. Katrina herself confirms that she is doing a Yash Raj film with Imran Khan and she is supposed to be cast in the female lead in Dhoom 3 under the same banner.
