Husband Ajay Devgn is shooting in Gujarat for Bhuj: The Pride Of India, so he is unlikely to make it to Mumbai for wifey dearest Kajol's big day. She turns 45 today.

Over the weekend, Kads was in Lonavla with mother Tanuja (who was seen in public after long post her surgery) and sister Tanishaa for a tree plantation drive. Not exactly known to be party-hearty, Kads will be keeping it low-key. One of the reasons also being that pa-in-law Veeru Devgan passed away in May. But son Yug has planned a surprise for mommy dearest.
