Hrithik and Sunaina are hosting a big birthday bash for their father Rakesh Roshan on September 6

Hrithik and Sunaina Roshan are planning a lavish bash for their father Rakesh Roshan who turns 64 on September 6.

The Roshans are in a mood to celebrate. They have their film Krrish 3 coming up. It also marks a decade since their first superhero franchise Koi..Mil Gaya released in August 2003. Plus, all's well on Hrithik's front after his recent health scare.

Says a source, `Sunaina and Hrithik have turned party planners for their dad's big day. They have already booked a place at Worli for the event. Invites are being sent to all their near and dear ones from the industry. All those who have worked with the filmmaker since the last several decades are also on the guest list.`


Adds the source, `They are planning to make a special AV for their dad. But they are keeping several things under wraps for what they have lined up at the bash. They want to keep some surprise elements for their dad at the party.`

Though the Roshans have celebrated birthdays and wedding anniversaries on the sets of their films, it has been a while since they hosted a bash for the who's who of the industry. Looks like they are now in a party hearty mode.
