Tim Allen has checked into a rehabilitation clinic as part of a court-ordered alcohol counseling sentence for drunken driving.

The "Home Improvement" star voluntarily entered a clinic Thursday, his spokeswoman, Marleah Leslie, said in Los Angeles. The location and name of the clinic weren't disclosed.Allen, 44, pleaded guilty last year to drunken driving. The actor, who has a home in Detroit, was arrested in May 1997 in Bloomfield Township, Mich., after his Ferrari was clocked at 70 mph in a 40-mph zone. Police said his blood-alcohol level was 0.15 percent, above the legal limit.
