Yes, that is right, I watch TB and she is playing a role in that serial on Zee TV. It is not entirely clear whether her role is positive (it looks negative) and she has not made a full "face" appearance. They only show her lips and her eyes, so one can easily guess our "Bhulakad".
But think about this, Charuballa, Dimple and now Praveena are on that show!
Let's hope that Praveena kicks some serious "Koki (Charballa)" butt on that show!
