A Hilton has gotten into trouble — and this time, it's not Paris. Instead her younger brother Barron, 18, was arrested yesterday on charges of driving under the influence and carrying a fake driver's license, according to authorities. Barron failed a field sobriety test and had a blood alcohol level of 0.14 percent (the legal limit in California is 0.08 percent). Since Barron is under 21, any blood-alcohol level is considered legally drunk. While the DUI charge is a misdemeanor, carrying a fake license is a felony. He was released last night on $20,000 bail and will be arraigned on April 14.
