Ash's item number with her ex, Viveik

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

The song will be shot in Rajasthan. Zayed Khan 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 , had also guest-starred in Lakhia's Shootout At Lokhandwala free of cost.

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