Paris Hilton has a hearing this morning and she could go back to jail.

Sheriff Lee Baca had ordered her release yesterday, and the city attorney filed a petition demanding that Hilton be returned to jail and to show cause why Baca shouldn't be held in contempt of court.

County Supervisor Don Knabe said he received more than 400 angry e-mails and hundreds more phone calls from around the country. Really? Those county supervisors are such super-stars.

Her hearing is set for 9 am. Stay tuned....
