Washington, Sep 4 (ANI): American actress Mila Kunis has revealed that she is going through a rigorous training regime to prepare herself for a role in the upcoming thriller ‘Black Swan’.

Kunis, 26, who reportedly engages in a racy girl-on-girl love scene with actress Natalie Portman, refused to say much about the story of the movie, and only revealed what she has been doing so far to perfect her role.

“I’m not allowed to talk about the script yet, but I’m excited to work with Natalie. I’ve known her for some time,” Fox News quoted her as saying.

“I’ve been studying for the past month, 7 days a week, 4-5 hours a day of doing ballet cardio and pilates and I have 2 more months before choreography begins. This ballet I’m doing you can’t fake it.

“Your body has to be structured differently, your hips have to be turned out, your shoulders have to be turned in, everything in your body is not natural, so I’m learning everyday,” she added. (ANI)
