Pakistani singer-actor Ali Zafar, who is looking forward to his upcoming movie "Mere Bother Ki Dulhan", has started working on his third Bollywood project called "London, Paris, New York", which he describes as a witty romance

"Announcing my 3rd film, 'London, Paris, New York' directed by Anu Menon, produced by Rose Movies presented by Fox star studios" Zafar posted on micro-blogging site Twitter.

The movie, being co-produced by Goldie Behl and his sister Shrishti Arya, has Adity Rao of "Yeh Saali Zindagi" fame as the female lead opposite Zafar.

"It's me and Adity Rao. Witty romance. Music and lyrics by me :) Today, we finished our London spell. Lucky to have such sweet producers as @GOLDIEBEHL and @shrishtiarya, " Zafar further posted.
