/> It's time for Katrina Kaif. It looks like she has decided to discard her habitually solemn demeanour to have some serious fun. And if ‘serious fun' sounds like a contradiction in terms it nonetheless describes her state of mind to perfection.

And if she has decided to be in the fun zone at the moment a lot of that zest to be happy comes from the company that she's been keeping lately. Imran Khan her co-star in Mere Brother Ki Dulhan has been "really cool company" for Katrina.

Says a friend of the actress, " Katrina found herself warming up not only to Imran but also to his family 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, "The 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 Mere Brother Ki Dulhan live concerts would be Katrina's first ever live concerts. Katrina can't wait.
