Chitrangada Singh has refuted rumours that she had differences with director Sudhir Mishra while shooting for "Sali Zindagi" saying it was just a "difference of opinion".

"There was nothing of that sort. It was just a difference of opinion about how we actually had to shoot a certain song in the film and the way I was playing the guitar in the same. But that was hardly anything, " Chitrangada told here.

It was reported that Mishra, who launched her in "Hazaaron Khwaishein Aisi", was irritated with her while shooting "Sali Zindagi" that was earlier titled "Dil Dar Badar".

The actress plays a musician in the movie that also stars Irrfan Khan.

"I learnt guitar before the shooting started. But that was hardly for 20 days... but I don't think I am comfortable with it or can strum it, " said Chitrangada.

Asked about the status of the film, she said: "It is a love story and is almost complete. It will release sometime in September."

She was here with Saif Ali Khan to unveil the new ad campaign for Brooke Bond's Taj Mahal tea. Saif is the brand ambassador for the product.
