Nikhil Arya seems to have a special spot for leggy beauty, Karishma Tanna. During the final concert of Sa Re Ga Ma Pa Challenge held last night at the Andheri Sports Complex, the duo was inseparable. Although, Nikhil had come to the venue long before his pal did, he made it a point to greet her at the gate as soon as she arrived. Karishma looked stunning in a pinkish orange saree, and together with Nikhil made a handsome pair.
