A few days after the Simbu-Hansika break up, speculations are rife about what really went wrong between the couple. Sources close to the actor are pointing fingers at Hansika’s mom, as the lady never approved of the relationship in the first place. The other being a difference of opinion between the lovers regarding marriage. Understandably, Hansika who currently riding a success wave in her career, isn’t too keen on settling down. But Simbu, we heard is keen on an immediate marriage. Then there is his film with his ex-flame Nayanthara that has not gone down well with Hansika. And the actors quite naturally would rather concentrate on their films than join these break-up theories.
