Former \"That\'s So Raven\" star Orlando Brown has begun his 180-day jail sentence in Los Angeles for driving under the influence, TMZ reported. The 25-year-old actor was remanded into custody Aug. 23 after he failed during a court hearing to show proof he completed judge-ordered alcohol-education classes related to his 2011 DUI arrest, the celebrity news website said Monday. He is expected to be released Sept. 19 because of jail overcrowding, TMZ said.
