Shruti Haasan has crooned with music composers Shankar-Ehsaan-Loy for a chocolate brand that she is endorsing. Of late, the actress seems to be concentrating on inking ad deals rather than looking at Bollywood offers. That she can also render the jingle helps. The chocolate ad has Shruti in a grungy look, belting out some hard rock. Shruti recently collaborated with Ehsaan-Loy for an independent single. She will be seen with father, Kamal Haasan, in upcoming Tamil film, Sabash Naidu.
