There’s going to be a new vamp in Sahara One’s Ghar Ek Sapna . There’ll be no addition to the cast but one of the existing characters will now show her true colours. Arzoo Govitrikar, who plays the character of Vanshika will now turn negative. Elaborating on Vanshika’s change in attitude, a source says, “Its’ a well known fact that Vanshika loves Sammaan (Ankur Nayar) but she couldn’t marry him. Sammaan’s mom Uttara (Himani Shivpuri) isn’t fond of her daughter-in-law Kakul (Sayantani Ghosh). So, Vanshika and Uttara plan to eliminate Vanshika. This new track will telecast from next week.” Arzoo Govitrikar remained unavailable for comment.
