It only took three days into the New Year for Britney to take back the spotlight from pregnant Jamie Lynn.

Earlier Thursday, the elder Spears finally decided to show up for a scheduled deposition with Kevin Federline’s lawyers.  (Keep in mind, she had somehow managed to skip out on a million of these appointments prior to today.)  After arriving approximately 90 minutes late, she left 15 minutes later.  It seems she didn’t like how she was being treated. 

Now fast forward a few hours….

As of 11:45pm PT, there is a large police and medic presence outside the Spears home in Beverly Hills.  Apparently the authorities were called to the house around 8pm when Britney failed to comply with her parental visitation guidelines.  (Kevin Federline’s bodyguards tried to pick up her two boys - Preston, 2, and Jayden James, 1 - as scheduled with no luck.)

After several hours of trying to resolve the matter “peacefully”, TMZ and Perez Hilton now are reporting that Britney has been taken away on a gurney for a mental evaluation.  This decision came after the police reportedly found her under the influence of some unknown substance. 

Meanwhile, both boys are apparently safe and back with their father.

Be expecting more to come..
