Megastar Mammootty, who has been entertaining us for over 50 years and continues to do so, turned 70 today. On the special day, Mammootty's son and pan-actor Dulquer Salmaan penned a heartfelt affectionate birthday note for his father on Instagram. Sharing a few lovely pictures with his 'Pa', the actor showered praises on his father. "I give up !! How does one even appear in the same frame and try to justify being there when you look like that ! Mashallah ! Ever so grateful and ever so blessed. I love you infinity Pa! We are the luckiest and most fortunate to be your family. We are constantly reminded of that when the world celebrates you on a constant basis. Wishing you the happiest of birthdays and may you always age in reverse. #Megastar #ActorExtraordinaire #SuperHero #WithoutACape #Legend #Mine #Ours #Everybodys #TheOG #LargerThanLife #YetTheSimplestManAtHeart #Best #Actor #Husband #Father #Grandfather #Son #Brother #Man #Definition #Love #HappyBirthdayPa"
