While shooting for Ramesh Taurani's ‘Toh Baat Pakki' –prankster Ahmed Khan decided to play a hoax on the newcomer Yuvika Chaudhary with Sharman Joshi's help.

We come to hear that Ahmed Khan took the lovely Yuvika‘s cell phone and sent Sharman Joshi quite an intimate text. He then told Sharman to play along.

Reveals a source, "At first Sharman was a little shocked with the message but when Ahmed told him about the prank he was playing on Yuvika -Sharman was game and replied to the text and scared the clueless Yuvika. Ahmed even went a step further and told Yuvika that the industry was a dangerous place and that she should take care of herself."

Vatsal Seth being equally clueless much to everyone surprise got very upset with Sharman- sources reveal that Vatsal has a soft corner for Yuvika and the prank didn't go down well with him.

Since then Vatsal started giving Sharman cold shoulder throughout the filming.

"Vatsal is a very fond of Yuvika and has quite a soft spot for her. He didn't appreciate the prank Ahmed and Sharman played on her. Ever since he has been indifferent towards Sharman," adds the source.
