Ali Zafar and Atif Aslam to sing their first song together

What happens when two of Pakistan's favourite pop stars get together? We'll soon find out.

Ali Zafar and Atif Aslam have jammed aplenty in the studio, but those sessions remain unseen and unheard. Now, the duo is planning to join forces for a song.

"The song is about friendship and unity. It's the first time the two superstars will collaborate on a song," says a source.

The song, which will be released soon, will have a video helmed by Yalghaar director Dr Hassan Waqas Rana. The song has been composed by Sahir Ali Bagga.
