After gracefully walking the ramp at Lakme Fashion Week, Kalki Koechlin took to the ramp yet again for designer duo Riddhi-Siddhi at the 'Style Walk'. The actress not just walked the ramp but also broke into an impromptu jig for the audiences. However, despite putting up an interesting show by the showstopper, Kalki has been called mentally disturbed by the designers as the showstopper forgot to walk the ramp along with them. According to a website, the designer duo was miffed with the actress as she was busy giving bytes to television channels when she was required on the ramp. The website also mentioned that the actress might be mentally disturbed as her marriage with director Anurag Kashyap is on the rocks. Hearing the news, Kalki took to Twitter to clarify her stance. "After a 4hour wait in lehenga, jewellery make up they have the gall to call me mentally disturbed! Riddhi siddhi, dp designers shame on you!" she tweeted.
