South Indian film stars, especially males, have gotten to choose from a limited range of products to endorse. After the likes of Mahesh Babu, Pawan Kalyan (whose stint as a brand ambassador was short-lived), NTR, Nagarjuna, Venkatesh, Akhil, Nikhil Siddharth, Madhavan, Suriya, etc., it is the turn of Siddharth to turn a brand ambassador again, years after endorsing brands like Idea`s Walking Raagas` as part of the Walk When You Talk` campaign, and Peter England.

He has endorsed Britannia's product Nutri Choice. Tweeting about the same, he said, "Happy to associate with #Britannia to endorse #Nutrichoice Digestive #biscuits. A household name from my childhood."

Siddharth awaits the release of his Tamil comedy-drama Jil Jung Juk.
