Completely rubbish. They have never faught. It is just a myth created by BB to make the audience ullu. BB wants to keep them both here for TRP so they made it just like Tina-Sreejita. In fact without Ankit there is no other issue for these 2 fight. Pryanka had better and bigger fight with Stan,Shalin or Archana than Nimmo.
Nimmo too has a cold war with Tina and Saundarya. Although when needed they help each other.
So far as a neutral viewer I have never found any good reason for these 2 to fight. BB forced them a lot of times. But alas. Kuchh big nehi huađđź
