Kangana Ranaut was spotted shooting a special number for Nikhil Advani's Katti Batti in Film City, Goregaon on Monday morning.

The 27 year old wrapped up the Mumbai schedule of the film with co-star Imran Khan and the two will be heading to Ahmedabad next month for the final schedule of the film.

Kangana who plays Payal, a bohemian art student, shot for over 12 hours for the song, while Imran, who steps into the role of Maddy Sharma, an interior designer, filmed till noon.

A set, recreating a 1970's-style Delhi house had been erected in Mumbai and the unit had been filming indoors. "We've maintained a retro look throughout the Mumbai schedule," says art director Amit Ray. "A weird incident takes place and the two stars are united by a twist of fate in this sequence," he smiles.
