Yet another Disney Star has been arrested for substance abuse. TMZ reported that "Lab Rats" star Billy Unger was stopped while driving on the Pacific Coast Highway in Malibu Saturday, just after midnight. Unger was pulled over for speeding, but deputies suspected that he was also under the influence. 

The 18-year-old actor also known for his role in "National Treasure: Book of Secrets" blew a .08 -- barely the legal limit. But he is 18, and California has a strict law against drivers under the age of 21 who have ANY alcohol in their system, resulting in Billy's arrest. He may also be facing more trouble soon because of the law's BAC above 0 percent for underage drivers. CaliforniaDUIPenalties.net explains that first-time DUI conviction can result to up to $1,000 in fines, a six-month jail sentence, license suspension and probation.

Unger was arrested, taken to jail and later released, though that doesn't mean he won't have to deal with the backlash this will bring to his career. The teenage actor now becomes part of a long list of troubled Disney stars, like Zac Efron, who completed some time in rehab not too long ago; Selena Gomez, who is alleged to have checked herself in for substance abuse and an addiction to Justin Bieber; Demi Lovato, who had several addictions during her time on the Disney Channel and is an advocate for recovery today. The list goes on and on from Shia LaBeouf to Jake T. Austin to Mitchel Musso and even Disney star veterans Christina Aguilera and Britney Spears.
