'That's So Raven' Star Orlando Brown -- Sentenced to 180 Days in Jail


It just keeps getting worse ... "That's So Raven" star Orlando Brown is behind bars, 2 weeks into a 180-day sentence ... in one of the craziest, most drawn-out DUI cases we've ever seen.

Law enforcement sources tell us, Brown was remanded into custody on August 23 following a hearing ... where he failed to show proof he completed court-ordered alcohol ed classes for his 2011 DUI arrest.

The only good news for Brown is L.A. County jails are way overcrowded -- so, he's expected to be released after only 27 days ... on September 19.

Brown's been crazy lucky until now -- in the last year 4 bench warrants were issued for his arrest, after he repeatedly failed to follow various court orders.
