Actress Nicole Kidman, who is to sing in a new musical movie "Nine", says she is terrified of singing and hates performing in front of people.

The 42-year-old star who recorded duets with Robbie Williams says that she is not a natural singer.

"I am terrified of singing. I am not a natural singer in the sense that I don't love getting up in front of a group of people and just belt out a tune. It needs to be coaxed out of me because I want my voice to tell a story and sometimes it doesn't have the capacity to do that," femalefirst.co.uk quoted Kidman as saying.

The actress felt particularly pressured because director Rob Marshall had told her that he envisaged her appearing as a "goddess" in the movie.

"When Rob approached me, he told me a role had been written especially. He told me he wanted her to look like a goddess and I was a little overwhelmed by that," she said.
