/> 'Jassi' Mona Singh turned 27 on Wednesday and she had a lot of reason to celebrate.

She has just been signed by Raj Kumar Hirani for a pivotal role in 3 Idiots.Apparently she has a track totally separate from the Aamir-Kareena one and also not featured in Chetan Bhagat's novel.

When contacted Mona who celebrates her birthday with her mother, is surprised.

"How do you know about this ? Ya, I am doing Raj Kumar Hirani's film. And I couldn't have hoped for a better birthday gift. What do I play ? All I can tell you is, I don't play one of the idiots. I play the sayaani (wise) character, ha ha."

Mona had to wait excruciatingly long for her movie debut. "A couple of projects that were meant to happen never did. But I'm glad Raju Hirani signed me. It's a fabulous role."

In the meanwhile Mona Singh is enjoying her stint on television as a dancer on Ek Khiladi Ek Haseena where she partners cricketer Harbhajan Singh.

"In fact Bhajji was one of the first to wish me on my birthday. We've become very close buddies. I think it's the Punjabi connection. He has a reputation for being hotheaded. I've quite a temper myself. So we're fine with one another."

Mona has been guiding Bhajji with his dance steps. "I've almost become his choreographer. He completely depends on me to see me through."

This may be the last dance show for Mona in a while.

And what about shaadi to boyfriend Karan Oberoi?

"I don't want to get married right now. I think I've just left Jassi behind. My career has just started."
