The Court's Lips Are Sealed

A rep for the court just came out of the hearing ... but can't tell us anything!

We're told that today's hearing with Jamie's lawyers and Brit's co-conservator is over, but court spokesman Allan Parachini tells TMZ, "Everything about this matter is sealed" -- and cannot disclose even why they are in court.

We have learned, however, that a motion filed today by Spears' conservator was unopposed, and that nothing has changed -- Jamie and attorney Andrew Wallet are still the co-conservators.

We're working on exactly what went down.
