Katrina Kaif and Ali Zafar making music

Katrina Kaif and her Mere Brother Ki Dulhan co-star, Ali Zafar, are all set to collaborate on a new music album, with the pair getting along so well on the set of their recent hit romcom, that sources say they're "beyond excited" to be heading into the studio to record some tunes together.

"Ali and I have definitely hit it off musically," said Katrina. "We share a lot of common musical interests that we're trying to take further. Let's see where it goes."

And Kat, who has already worked with uber-producer, A R Rahman, singing nursery rhymes on their 2010 children's album, Rhyme Skool, also boasts some pretty good guitar skills, having been taught by Farhan Akhtar during the filming of this year's Zindagi Na Milegi Dobara.
