Mumbai: It looks like Katrina Kaif has decided to discard her habitually solemn demeanour and have some serious fun -- by promoting her upcoming film `Mere Brother Ki Dulhan`.
Her desire to be in the `fun` zone may have lot to do with the company she is keeping lately, especially her `Mere Brother...` co-star Imran Khan.
Says a friend of the actress: "Katrina found herself warming up not only to Imran but also to his wife Avantika. She felt she was part of a family."
And the `family` has convinced Katrina to go on stage for what is secretly being termed the `Dulhan` gigs.
Says a source: "`Mere Brother Ki Dulhan` producers Yashraj plan to put Katrina, Imran and Ali Zafar on stage to promote the film. Ali, who plays one of the leads, asked Katrina if she too would accompany him for the gigs that would take them to several metros. At first, Katrina laughed off his suggestion. When Ali was adamant she wanted to know what she would do on stage. Ali suggested she join him to sing. And Katrina is game."
As things stand, the gigs will be Katrina`s first ever live concerts.
