Rajesh Khanna and Twinkle Khanna share a birthday December 29th. So there's always reason for a double celebration on this day in the Kumar-Khanna household.

Actor Akshay Kumar, husband to Twinkle and son-in-law to Rajesh Khanna, has ensured that today remains a day to remember for the birthday boy and girl.

The actor has taken the entire family to Goa, and intends to celebrate Rajesh Khanna's birthday in the land of sand and surf.

If sources are to be believed, there are about 25 guests - family and close friends - who'll be in attendance. And that's about it!

Dimple Kapadia and her younger daughter Rinke with her family will also be there to wish Rajesh Khanna and Twinkle 'Happy Birthday'.

We also hear that Akshay has some surprise gifts in store to make the day bigger and more special. The family and friends intend to bring in the New Year in Goa itself.
