Rebecca Ferguson's seven-year-old son asked her about strip clubs after listening to Rihanna.

The former 'X Factor' star, who has returned to her native Liverpool with her two children, Lilly May, nine, and seven-year-old Karl, said they are growing up quickly and she found her son's comments ''scary''.

The 27-year-old said: ''The other day my boy came and asked me about strip clubs after listening to a Rihanna song on the radio.

''Some things you can't stop them hearing sometimes, but it's your responsibility to say, 'That's too old for you.' He's only seven. That's scary, I wouldn't have known anything about that at that age.''

Rebecca, who keeps her partner of a year out of the limelight said the pair would like to have a baby together before she turns 30.

She said: '' I'd like to be pregnant at 29, have the baby by 30, then release another album at 31.

''Who knows what will happen, but in an ideal world that's what I'd like.''

Rebecca also reveals that she enjoys staying out of the spotlight.

She added to HELLO! magazine: ''At home it's normal. We're like a gang of scruffs and we just lounge around in our PJs on my day off.''
