Bollywod actress Sonakshi Sinha is playing a dual role for her upcoming film Son Of Sardaar (SOS).
Apart from acting in the movie, she is also proving to be quite a marketing guru.
Sonakshi has been actively involved on social networks to promote her film with interactive and engaging updates.
For the launch of the recent song Bichdan, Sonakshi tweeted to her costar Ajay Devgn, "#SoS size romance is here - http://bit.ly/BICHDANN @ajaydevgn sardaarji.. kadi hans bhi liya karo.. Hanste huve bada accha lagta hai tu :)"
The response to the song release was quite well as the views were stuck in only ten minutes post the launch.
After the successful song release, Sonakshi went a step ahead by launching a Facebook contest with a tab called "Make Ajay Smile".
She announced that anyone who succeeds in bringing a smile on Ajay's face will stand a chance to meet him and the cast of Son Of Sardaar.
Starring Ajay Devgn, Sanjay Dutt, Sonakshi Sinha and Juhi Chawla, the film is slated to release this Diwali on November 13.
