According to reports, friends and family have been asked to keep their date books free from 11 to 14 December.
And Vidya has taken a fortnight's break from the shooting of Ghanchakkar in December.
The actress has also turned to her favourite designer Sabyasachi Mukherjee to create her wedding trousseau.
According to the rumour mills, Vidya has already placed an order for 18 hand-crafted saris with the designer. Since the bride and groom will be combining both Tamilian and Punjabi wedding rituals, Vidya will need quite a few sari changes!
And Sabyasachi is leaving nothing to chance. Reports have it that he will be going to Chennai personally to source Madras silk for the wedding sari.
