Tamil superstars Karthi and Suriya are the sons of veteran actor Sivakumar. The two brothers has carved their own space in Kollywood and command massive fandoms. They also share an unbreakable emotional bond. Karthi once talked about how his elder brother Suriya is like a 'little dad' to him.

Karthi, who is two years younger than Suriya, had said that the two brothers used to get into massive fights when they were younger. But things got better after they spent some time apart. "Until I left for the US to study, we both had best and worst of fights. We used to roll on the floor, that’s how bad it was (laughs). We used to fight for cars, clothes and two boys in the house, you can imagine it was fireworks always," Karthi had told Pinkvilla in an interview.
