Britney Spears has been taken from her house by ambulance, police have confirmed.
A Los Angeles police officer told Associated Press that the 26-year-old pop star was being taken to "get help" but did not say where the ambulance was going.
Earlier this month, Spears was taken to a Los Angeles hospital by paramedics after police were called to her home because of a dispute involving her sons, Sean Preston, two, and Jayden James, one.
She has lost custody and visitation rights with the boys.
Police also went to the house on Monday night after someone reported paparazzi trespassing in the singer's gated community.
When officers arrived, they didn't see anyone trespassing, police said, but citations were issued for several illegally parked cars.Spears has been in a highly public downward spiral since filing for divorce from Kevin Federline in November 2006.
