Mumbai, Jan 4 Actresses and sisters Gauahar and Nigaar Khan have revealed each other's secrets and habits online. Nigaar appeared on Gauahar's new YouTube channel on its second episode on Wednesday. "Everyone wanted the Khan sisters back for a very long time and since we were not doing the show, I have started my YouTube channel. I just thought it will be a great way to give a dose of our craziness to our fans. "That is when I thought of getting my best friend, my sister and my better crazy half on the show. It was the craziest episode we shot for the channel. It felt like we relived the moments of 'Khan Sisters'," Gauahar said in a statement to IANS. TV show "Khan Sisters", which put the spotlight on the two sisters, went off air five years ago.
