A R Rehman is once again headed for the Oscars. But this time around it’s not for an Indian film, but a Hollywood film called “Couple’s Retreat”. Rehman is nominated in the “Best Original Song” category. The song is titled “Na Na…” and is close to his heart because it marks the debut of his six year old son, Alim, who has sung the track. And this is also the first time A R Rehmaan has composed soundtrack for a Hollywood film. 'Na Na' was written by Rahman along with rapper Blaaze and Vivian Chaix and sung by the trio along with Alim, Clinton and Dominic Directed by Peter Billingsley, the film is a comedy centred around four couples who settle into a tropical-island resort for a vacation. While one of the couples is there to work on the marriage, the others fail to realize that participation in the resort's therapy sessions is not optional. Rehman was recently nominated and awarded the Oscars for his soundtrack in “Slumdog Millionaire”.
