The sexy babe Kareena Kapoor has started her wedding preparations already and the first thing she has shopped for is her wedding jewellery. Seems like Saif Ali Khan and Bebo are all set to have a royal wedding and the arrangements are in full swing. Apparently the RA.One actor has ordered for a customised precious gems studded necklace that runs from the neck to the waist. And guess what? The exotic neck-piece will take two months to finish. Meanwhile, we hear that the nawab is planning to gift his begum a big diamond ring. We are sure that the 400gms of bling will definitely make Bebo look like the quintessential Pataudi begum.
