India, Aug. 3 -- Kalki Koechlin and Gulshan Devaiah's bond began not on film sets, but in green rooms and after-show hangouts. What started as effortless camaraderie, free of pretense or pressure, has quietly "evolved into a deep, enduring friendship" - the kind where you're not just close, you're family. As today marks Friendship Day, the duo shares all about their first meet, bond, highs-lows, and more. Kalki recalls, "We've gone on holidays together, seen each other through rough times. We were once at a house party, and as soon as the song from the movie Fashion - 'Fashion ka Jalwa' played, we went wild. That was the moment we knew we'd be friends forever." Turn Over to Page 6...
