The whole thing went down around 10:50 this morning when private security noticed 26-year-old Miranda Tozier-Robbins acting suspicious outside of the home. According to the incident report, security asked her to leave, but the woman "balked at their requests" and had to be physically escorted off the property.
Sheriffs arrived shortly after and took her to a local station where she was booked on charges of trespassing and disorderly conduct. Bail was set at $5,000, but she was released on a citation to appear in court on June 16.
We're told Britney was not home at the time, but she is in town this week -- playing the Staples Center in Los Angeles tonight and tomorrow.
