Veteran actor Dharmendra on Saturday congratulated his son Sunny Deol on the success of `Gadar 2` and was ecstatic about its box office performance, and thanked audiences for making it a blockbuster.

Taking to his X account (formerly called Twitter), the actor posted a picture of himself and wrote: "Dosto, qismat wala hota hai Baap woh…jis ka beta kabhi jab Baap ban kar bacchon sa laad ladata hai (Friends, it is only a father with great luck who gets to see his son, when he becomes a father playfully fight with his children)."
