New Delhi, July 9 -- Kareena Kapoor has three films under production - Shah Rukh Khan's Ra.One, Saif Ali Khan's Agent Vinod and Rohit Shetty's Golmaal 3, but she insists that she won't work on any other movie while shooting for Madhur Bhandarkar's Heroine.

Inspired by the life of Hollywood diva Marilyn Monroe, Bebo feels the role is tailor-made for her.

"I've been a heroine since I was in my mother's womb. I eat, drink and breathe acting," she says.

The actress feels this is the right subject for her and Bhandarkar to work together on. "I'll give my heart and soul to just this one film once it goes on the floors, since it is a performance-oriented role."

Though taking on Monroe is a "scary proposition", Bebo says she's ready. "We'll be adapting some of Marilyn's famous roles. There will also be moments from her headline grabbing personal life, which may be emotionally draining, but I'm ready for it."

Won't she have to put on a few extra kilos for the role? "I'm quite healthy now, thank you. No more size zero for me. I don't mind putting on 10-12 kilos if I'm not doing any other movie at that time."
