Bong bombshell Tanushree Dutta has been so busy with her Bollywood assignments that she never exploited her potential as a model after winning the Miss India title. But finally, the actress has stepped onto the "brandwagon". She has signed her first lucrative endorsement of a high-profile jewellery brand, previously backed by the divas of Bollywood.Tanushree is tight-lipped about the brand, but she says: "It's an honour to be a brand ambassador. Till now I was busy establishing myself in Bollywood. But now, it's the right time." The buzz is that the actress has bagged offers of many more such assignments. Looks like Tanushree is on an endorsement spree.
