As Rani Mukerji turns 47, we revisit a gem from our Sit With Hitlist vault. In this throwback, she opened up about how motherhood has transformed her, her initial insecurities about her voice, and a memorable story about Aamir Khan asking her to dub for `Ghulam.` She also shared how Aamir later regretted it when Karan Johar made Rani use her own voice in the iconic superhit movie Kuch `Kuch Hota Hai.`
