Jewellery designer Farah Khan Ali was amused when she saw copies of her designs in Ahmedabad and said that "imitation is the best form of flattery". Farah, daughter of actor Sanjay Khan and Zarine Khan, was in the city on Saturday to participate in Jewels of Asia, an event where well known designers participate. "Exhibiting at Jewels of Asia in Ahmedabad among 10 other jewellers and brands. (I am) amused to see copies of my designs at a next door exhibitors' stall," she tweeted. "Guess, you know you are famous when someone is making copies of your designs. Imitation, the best form of flattery," she further tweeted. She was recently in the news when international pop star Beyonce Knowles chose to sport one of her crowns in her music album "4". Her jewellery pieces were also endorsed by tennis player Serena Williams as well as music composer A.R. Rahman's wife Saira, who wore one of her designs at the 2011 Oscar ceremony.
