Siddharth Malhotra From \u2018not\u2019 to \u2018hot,\u2019 Siddharth owes puberty his heartfelt and eternal gratitude. Kajol While there is no denying her caliber as an actress, Kajol similarly owes the person who invented makeup one helluva thank you. Kangana Ranaut We\u2019re glad that the Kangana of today got over her aversion to the camera and took to the silver screen with some absolutely brilliant roles, because Kangana Jr. sure doesn\u2019t look too cheesed about being on the receiving end of the camera lens. Priyanka Chopra With absolutely zero offense to Priyanka, it\u2019d take one hell of a fortune teller to predict that the kid in this picture would one day bring the Miss World crown home and bedazzle the Indian and Western masses alike. Imran Khan We\u2019d have had a hard time connecting the cute little guy in this picture to Imran Khan, but mercifully those thick brows saved the day. Shilpa Shetty Graceful, stylish and hot, everything that the younger Shilpa was not. Bappi Lahiri Damn. For a minute there, we almost didn\u2019t connect this innocent young kid to the walking, talking gold van he has morphed into today. Kapil Sharma For a celebrity of his caliber, Kapil is as appearance conscious as the next guy, but guess how many Babaji Ka Thullus he gave about his looks back in his childhood? Alok Nath Contrary to what we always thought, Alok Nath didn\u2019t just spring into existence as the beaming, benevolent Babuji of today. Back in the days of yore, before he singlehandedly took on the task of wiping out the country\u2019s singles registry, Alok Nath looked like he was ready to dole out anything but aashirwaad to the ladies.
