With just a week away from its release, producer Twinkle Khanna has come up with the 'PadMan Challenge' and the first person who dared to take it up is Mr Perfectionist, Aamir Khan. The actor took to his Twitter account to share a photo of himself holding a sanitary napkin. He is happily flaunting the pad and isn't ashamed of it at all! The 'Dangal' star wrote, "Thank you @mrsfunnybones. Yes, that's a Pad in my hand & there's nothing to be ashamed about. It's natural! Period. #PadManChallenge. Copy, Paste this & Challenge your friends to take a photo with a Pad. Here I am Challenging @SrBachchan , @iamsrk & @BeingSalmanKhan (sic)."
