Actor Uday Chopra finds rumours of a relationship with Yash Raj Films (YRF) discovery Parineeti Chopra ridiculous. "Whoa! Parineeti Chopra and I are not dating guys. It's kinda ridiculous! And she doesn't call me sir, though I think she should start," tweeted Uday.

Parineeti's Bollywood career kicked off with Yash Raj Films' (YRF) Ladies vs Ricky Bahl. She followed up its success with Ishaqzaade. Meanwhile, Uday is looking after the banner's Hollywood wing -- YRF Entertainment, which develops and produces feature films for the US and international market.

The duo were spotted enjoying together at various nightspots, sparking rumours that there's something beyond a professional camaraderie.
