Hot Shilpa Shetty is all set to Shut Up and Bounce. Yes that's the song of Tarun Mansukhani's Dostana that has just come on air.

Director Karan Johar said that Tarun and he and his entire team brainstormed tossing names of actresses who would be apt for the item.

"We finally zeroed in on Shilpa because she has the best body in town," Karan said.

Karan added, "Shilpa has done a fantastic job but credit also goes to choreographer Vaibhavi Merchant and music directors Vishal Shekhar. Shilpa's number will be the introductory song along John Abraham and Abhishek Bachchan."

Tarun said, "Shilpa was comfortable wearing anything for the song. We were to shoot the song in seven day but completed in four days flat."

Shilpa agreed to be a part of Dostana immediately because not only was it a Karan Johar production; it also had her favorite team of designer Manish Malhotra, Mickey Contractor for the make up and Latika for her hair.

And though her bag went missing, Shilpa along with Manish shopped at Gucci, Dolce & Gabbana and got herself ready for the song.
