The youngest star of "Home Improvement," Taran Noah Smith, has left show business, but he's still making headlines. Smith, who played the youngest of Tim Allen's kids on the '90s sitcom, was arrested Feb. 1 and was later charged with driving under the influence and possession of hashish. Last week, Smith pleaded guilty in California to drug possession and no contest to a "wet reckless" charge (which replaces a DUI in a plea-bargained settlement), according to On The Red Carpet. His sentence included a six-month drug-diversion program, three years probation and a fine. The actor, 27, has stayed off screen since "Home Improvement" ended in 1999, but he has had his share of real-life drama. He sued his parents in 2001 over the money he made on the sitcom, alleging that they were using his trust fund. Smith married Heidi Van Pelt, 32, in 2001 and the pair opened a vegan restaurant called PlayFood in California. They had a son, Nolan Eric Smith, before divorcing in 2007.
