Southern actress Hansika Motwani and Tamil actor Silambarasan aka Simbu have confirmed that they are in a relationship. However, Simbu says any decision related to their marriage will be taken by their respective families. Hansika had been rubbishing rumours about her link-up with Simbu, but she has finally opened up on micro-blogging site Twitter. "(I have) been hearing many rumours about my personal life, so just want to clear (the air).Yes, I'm seeing STR (Simbu) and hence I wouldn't like to talk about my personal life," Hansika posted on her Twitter page. Confirming the news, Simbu posted on Twitter: "Yes, I'm with Hansika and right now she is doing really good and marriage will be decided by our family. (I) hope you will respect our privacy". Ever since the duo started shooting for Tamil films Vaalu and Vettai Mannan, it was reported that they had developed fondness for each other. While Simbu is busy shooting for Vaalu, Hansika is now busy wrapping up Tamil comedy Biriyani and Telugu untitled multi-starrer with Vishnu Manchu.
