Ciara is expecting a baby boy.

The 'Goodies' singer is due to give birth to her first child with her fiancé Future next month and the 30-year-old rapper may have let slip the sex of the unborn tot.

During an interview with Tim Westwood TV, he said: ''The baby's listening to music already now. [Ciara] sent me a video while I was over here with the headphones on her stomach. She's like, 'The baby just listened to 'Turn on the Lights', the version with me and you.'

''I said, 'You gotta play the 'Anytime' for him, the new one you did. Let him hear that, see how he kicks'.

''She played it and he started kicking crazy.''

Meanwhile, the 28-year-old star has remained tight-lipped about whether she is carrying and boy or a girl over the past four months, but recently admitted the gender didn't initially match her ''preference'' when she found out.

She said previously ''I did have a preference before I found out what it was. I had a preference at first and when I was told what it was, I felt it's going to be what it's supposed to be.''

However, Ciara insists Future - whom she got engaged to in October last year - was pleased when the sex of their child was revealed.
