Looks like all those rumours about Arshad Warsi and Dia Mirza being more than just friends are true. Arshad almost proved it recently when he showed his ire over a journalist"s nasty remark.
The Hum Tum Aur Ghost actor-producer lost his cool when a reporter asked him why he had signed on Dia, a flop actress, for his maiden production venture. Arshad, who was being very cordial until then, started to reprimand and abuse the journalist. He was about to raise his hand on the reporter but stopped himself on time. However, as he was still angry over it, he left for a smoke break and stormed out.
So, maybe Arshad and Dia are more than just co-stars. It certainly looks like it.
