Dhanush is one of the biggest superstars down south, but that doesn`t make him any less of a star in Bollywood. Dhanush, who made his big Bollywood debut, surprised everyone by delivering `Raanjhanaa`, and firsts are always special. For Dhanush, his first is very special not only because of the movie but also because of the co-star. Dhanush made his Hindi film debut opposite Sonam Kapoor, and he adores her very much, more than his second co-star, Sara Ali Khan.
It`s not us saying that Dhanush likes Sonam more than Sara; he himself said this to Karan Johar during one of the promotional events for his second Hindi film `Atrangi Re`. In a chat during `Koffee Shots With Karan`, Dhanush was asked to pick between Sara and Sonam during the Rapid Fire round. Reverting to the question, Dhanush picked Sonam, to which Sara quickly replied, "Wow, not offensive at all."
