Actor-singer Ali Zafar has rubbished rumours of a rift with co-stars Imran Khan and Katrina Kaif. Rumours of the rift began making rounds after his absence was noted at the music release of ‘Mere Brother Ki Dulhan’. Ali explained that he could not take part in the release as he as was in London for a film shooting. He also added that once he is back in town, he would have a live promotional concert with Imran and Katrina. The stars are planning to do many such live gigs across the country as a promotional tactic. In a song ‘Madhubala’ sung by Ali himself, he is seen tossing glasses of bhang performing a hip version of ‘Bhangra’ along with Imran and Katrina. Speaking about the track, Ali said, “It’s a fun track that we shot over four days in Mumbai in sweltering June. Since I don’t drink, I didn’t touch the ‘bhaang’ but downed glasses of cold coffee. I lost four pounds in four days.”

Between takes on the sets of the movie, Ali used to teach Katrina to play the guitar. He said, ““I taught her a few chords. She was a diligent student during the shoot but I don’t think she’s practiced much after that,” he says. Kat is also seen sporting a bad girl look in one of the songs in the movie. Ali muses, “I was the one who urged her to go in for a more grunge look as opposed to her usual squeaky clean appearance. Dark under eye make-up, leather and boots. It’s gone down well.”
