Kangana Ranaut is facing some real tough time these days. Her personal assistant on Wednesday filed a complaint with police that he was receiving threatening calls from a person in this city.

Shrikant Sridhar Sawant, 34, filed a complaint at Bhoiwada police station that said a man identifying himself as don Mayraj had been calling him repeatedly since Tuesday and threatening him, police said.

According to the complaint, Mayraj asked Sawant to send the actress to him for an "overnight stay" and assured him a sum of Rs five lakh for the same.

"In case Sawant did not send Kangana, Mayraj threatened to kill him and throw acid on her face. Due to this, a complaint of criminal intimidation was filed today," said a senior police official.

On professional front, her Shakalaka Boom Boom sank without a trace but it seems she has learnt her lesson pretty well. The pretty lady has taken her co-actor Bobby Deol's digs on her dancing very seriously.

So when Bobby expressed his feeling about Kangana's dance ability while shooting for Shakalaka Boom Boom, Kangana did not let it dishearten her and took the criticism in her stride by joining dance class to groom herself as a dancer.

The actress says. "No one is a trained actor in this industry. Everyone learns and gradually perfect their skills."

The actress has joined Jayantimala's dance academy in Mumbai and she is learning Kathak.

Kangana's guruji Jayantimala is the daughter of famous Kathak exponent Sitara Devi.

She thought to groom herself in classical dance, as it's considered to the basic of any form of dance. She is also not learning dance for any particular film and is doing it for herself.

Bobby had apparently poked fun at Kangana's ungracefull dance steps,to whioch Kangana responded bty taking up

Kathak which is one of the oldest and traditional form of dance from Benaras with lots of grace allowing you to handle all forms of dance. I Kangana is religiously practicing dance everyday. for more than a hour.

It was also reported that Kangana has kept a tutor to brush her Hindi, so that she can dub her own dialogues.
