This is getting insane! Cops and ambulance arrived at Spears' home, a stretcher was taken in and PageSix.com is reporting that "someone is being transfered to the hospital for a mental evaluation."
Apparently Britney was "hysterical and just wants to keep the kids overnight."
The ambulance is leaving Spears' home RIGHT NOW!
Sam Lufti was just seen leaving Spears' home with an officer.
