Twinkle, who bid adieu to the big screen in 2001, is making a guest appearance in the movie which will release in December.
"The sequence filmed on the couple is a comic one starting out with Twinkle walking the red carpet and Akshay butting in and trying to steal the limelight only to have himself pushed out of the frame. It was shot impromptu, no retakes were done since the scene turned out to be very funny, " said a source.
Akshay Kumar's Hari Om productions has co-produced the film along with Shirish Kunder's Three's Company and it has Akshay, Katrina Kaif and Akshaye Khanna in the lead roles.
