Sweating it out on the sets, Akshay Kumar says dancing for upcoming 'Rowdy Rathore' is killing him. Being trained by none other than Prabhu Deva himself, Kumar says meeting Prabhu Deva's dance expectations is no joke. "Prabhu sir is truly killing us, making us dance like true South Indians, which is why Sonakshi Sinha is hiding," wrote Akshay on his blog.
