It sounds unbelievable but a little birdie informed Gullu that Viveik Oberoi will do an item number with his ex-girlfriend Aishwarya Rai [Images], and her husband  Abhishek Bachchan [Images] in Mission Istanbul.

The song will be shot in Rajasthan. Zayed Khan [Images] will also be a part of it.

The reason the Bachchans have agreed to be a part of the Viveik-starrer was because of Abhishek's friendship with director Apoorva Lakhia.

Abhishek had starred in Lakhia's first film, Mumbai Se Aaya Mera Dost. He, as well as Amitabh [Images], had also guest-starred in Lakhia's Shootout At Lokhandwala [Images] free of cost.

That's probably why they say dost ke liye kuch bhi karega in Bollywood.
