Karan Johar turned 53 on May 25 and celebrated in true KJo fashion, draped in diamonds, armed with one-liners, and flanked by his best friend Farah Khan. A fun birthday video shared on social media quickly went viral, not just for the glittering jewellery but for the effortlessly funny banter between two of Bollywood's most beloved personalities.Farah Khan kicks off the funThe video opened with Farah setting the tone with a playful dig, introducing herself and Karan with, "Hi guys, I'm with the birthday boy, fresh from the Met Gala and not of Lokhandwala."Never one to be outdone, Karan fired back, "And everyone's aunt, Farah. Thank you for inviting me to your quick one-minute show."Things got particularly entertaining when Farah clocked Karan's dazzling necklace and could barely contain herself. "And now Karan has started wearing his mother's jewellery. Oh my God, these diamonds," she exclaimed. Karan, completely deadpan, responded, "It is said that a mother's feet have heaven and her safe has a necklace. And a mother's necklace has victory."When Farah pressed him on whether the jewels were expensive, Karan quipped without missing a beat, "They are as expensive as your wardrobe, Farah."Farah, in her trademark style, landed the final punch, "Oh God, so cheap diamonds. Okay, but happy birthday, Karan." Karan signed off in his signature style with a cheerful, "Toodles. Bye." Bollywood pours in the birthday loveBeyond the viral video, several Bollywood A-listers took to social media to wish the filmmaker. Kajol shared a candid picture and wrote, "Happy Happy birthday Karan. Most of the pics we have together are blurry, probably because we both can't stay still long enough."Kareena Kapoor Khan posted a monochrome picture with the caption, "Love you Love you and love you more, today and always. Happy birthday my darling @karanjohar."More about Karan JoharOver the decades, he has helmed some of Bollywood's most emotionally resonant blockbusters, including 'Kabhi Khushi Kabhie Gham', 'Kabhi Alvida Naa Kehna', 'My Name Is Khan', 'Student of the Year', 'Ae Dil Hai Mushkil', and most recently 'Rocky Aur Rani Kii Prem Kahaani'.
