Riddhi siddhi,dp designers,shame on you. I did not walk away from the ramp.

This move of hers had angered the designers and they had allegedly called her mentally disturbed. However,Riddhi and Siddhi said they had never called the actress mentally disturbed and insisted whatever is being said about them is untrue. (With PTI inputs)
