However, Riddhi and Siddhi have rubbished claims that they called the actress mentally disturbed and insisted whatever is being said about them is untrue.
"We are shocked to see this accusation from her. We would never stoop down to talk about anyone this way. We were glad that Kalki was sporting our garment on ramp as we think she is one of the best dressed style icon in Bollywood," the duo said.
"It was primarily a jewellery show and not a clothing one. She was supposed to walk with jewellery designers," they added.
The duo are miffed with Kalki for dragging them into this without checking the facts.
"We do not need such kind of publicity by putting someone else down. The least Kalki could have done was to ask her agent to call us before putting matter on twitter," Riddhi commented.
"We need an officially apology on Twitter and other media about the same as she has been responsible for defaming us for no reason," the duo said.
