"I have always admired Preity for her drive and guts in a world that can be most cruel to a single girl. But just look at the way she has managed her career, all alone, without any traditional assistance from the industry," Amitabh wrote on his blog bigb.bigadda.com.
"She is frank and painfully honest and outspoken to the 'o', and that is an admirable quality for a girl that had to face some rather tragic and unfortunate events very early in her life."
"She put her hand into business, knew nothing about it, but was determined to educate herself. So she went across to US for a short course in business management at a prestigious college (Harvard Business School) and came back wiser, educated and a lot more confident and not for a moment keeping too far away from her profession of choice - films!" he added.
Amitabh was invited by Preity to a party thrown by the French embassy in honour of Isabelle Adjani, who is shooting with the actress for his debut production venture "Ishkq In Paris".
"Preity Zinta produces and acts in a film which also has in its cast the beautiful Isabelle Adjani from France. Isabelle is in town for its shoot and Preity invites us for a party at the Sofitel Hotel, hosted by the French Ambassador, to meet the lovely lady. Its a quiet dignified evening, and because I am fond of Preity, I go along for precisely 10 minutes, to wish her and her guest," he posted.
