Spears breaks another road law

Troubled pop star Britney Spears was stopped by police in Los Angeles on Monday - after her Vehicle Registration Tag expired.

The 'Toxic' hitmaker was leaving nightclub Winston's in the city on Monday night when she was handed a warning by officers.

Spears' pal Alli Sims was overheard telling officers: "We'll get one this week, she just got this," reports website TMZ.com.

The 26-year-old already faces charges of driving without a valid California licence and earlier this month ran over a videographer's foot.
