X17 photographers have been in touch with Britney's childhood friend and former assistant Alli Sims and she tells us she is on her way to Brit's home right now.
She would not comment further on the evening's events.
UPDATE - Police on the ground and an LAPD helicopter are still on the scene, two hours after they arrived tonight.
Let's hope Britney just passed out after not sleeping for almost three days!
