Riddhima Will Come Back In Omkaras Life

I had read this a few months ago on Shireenas Twitter. A fan asked her if Riddhikara is over and she replied "not so so soon my dear" and she mentioned that Riddhima will be back after some time. So am guessing after Omkaras Love story begins Riddhima will come to create trouble as she was with Om for a long time.
After Riddhikara breakup they hardly showed anything about them. So with Omkaras story in DBO am sure Riddhima will turn grey.
What do you guys think will Riddhima come back ?

Riddhima may turn black cuz we already have Gauri who will be grey.
