Vidya Balan and Riama Sen share a special camaraderie. The two were caught together giggling away to glory during the screening of Parineeta recently. The two met up at the Vidhu Vinod Chopra film festival held in the surburbs recently.

An eyewitness said, "Raima kept whispering in Vidya's ears and Vidya kept laughing. Ever since the two met during Parineeta, Vidya and Raima have been great friends."

A source said, "The two always make it a point to catch up whenever they can. They dine or at times catch up at a coffee shop in the evenings. It is a very rare to see two actresses share this kind of a camaraderie." The actresses have no qualms just hopping in an autorickshaw and meeting each other.

"The two enjoy using public transport at times just to meet up. For both, friendship is all about meeting up whenever and whichever they can. Vidya and Raima know that they can always depend on the other. It is this 4 am friendship that has bonded them closer."
