The teen idol and singer from the 1970s, David Cassidy, was arrested in Florida on a DUI charge Wednesday evening. Police arrested Cassidy after he was caught driving erratically in his white Mercedes. Police say they smelled alcohol on his breath. Cassidy said he had a glass of wine at lunch and a hydrocodone tablet later in the afternoon. However, he blew a .14 on a breath test, and police found a half-full bourbon bottle in the back seat of the vehicle.
