Britney Spears has reportedly rubbished husband Kevin Federline's hopes of becoming a pop star - and laughed at his first recorded efforts in the studio.

According to a report in In Touch Weekly magazine, Federline - who met the singer when he danced on one of her tours - was hurt by his spouse's response to his attempts to sing.

The magazine quotes an insider who claims Federline's songs were "greeted with hurtful laughter from his superstar wife, who was unimpressed".

The insider adds, "She said his debut CD might sell 'a hundred, maybe a thousand' copies if he was lucky... Kevin looked really hurt."
