Things went from bad to weird to worse for Britney Spears last night. Click RIGHT HERE NOW for a report on what went down after police were called to transport Brit -- referred to as "the package" -- to UCLA Medical Center after a tumultuous evening that included ... hot chocolate.

Oh, and her mom Lynn Spears drove to the hospital with ... Adnan!

Guess he's back in the picture and Sam's out?

Anyway, last report is that a 5150 has been signed by an L.A. judge and Britney is on a three-day hold for evaluation.  Click HERE for more.

Could there be a light at the end of Britney's trainwreck tunnel? Hope so!   

Stay tuned!
