For an actor who is as unconventional-looking as Dhanush it is quite an achievement to be endorsing a beauty soap. But that is exactly what Dhanush did, when on Tuesday he flew into Mumbai after a flash promotional trip to Chennai to promote his new Tamil film Maryan, to shoot an ad for Lux with the very beautiful Sonam Kapoor. Says a source from the sets, “Initially Dhanush who is extremely self-deprecating about his looks was aghast at the idea. ‘How can I endorse a beauty soap?’ he argued. But it was his new buddy in Mumbai Sonam who convinced Dhanush to give it try.” On Tuesday the Raanjhanaa pair shot for the ad amidst loads of bantering and rejoicing, now that Raanjhanaa has been declared a hit. Says Dhanush shyly, “It was different experience, but fun for me.” The Raanjhanaa director Aanand Rai was also present during the shooting of the ad. “I just looked at the two of them proudly. When we began shooting Raanjhanaa everyone wondered what kind of a pair Sonam and Dhanush would make. Now they’ve been unconditionally accepted as an on-screen couple,” said Aanand emotionally.
