Posted 8/8/07 - Troubled actress Lindsay Lohan has entered an alcohol rehabilitation centre for the third time this year following her arrest last month for drink-driving.

Lohan, 21, has checked into the Cirque Lodge drug and alcohol treatment centre in Utah for an intensive 30-day program, CBS television's The Insider entertainment show reports on its website.

The actress arrived at the facility over the weekend, The Insider reports, citing sources within the facility.

Lohan's representative Leslie Sloan was not immediately available to comment.

Lohan, the star of Georgia Rule and Herbie Fully Loaded, was arrested in California for drink-driving and drug charges on July 24, just days after completing a stint in rehab following an arrest in May on similar charges.

Lohan has already undergone two separate spells in rehab this year.

In January she was treated at the Wonderland Centre in Los Angeles after reportedly being found passed out in a hotel corridor following the Golden Globes awards in Beverly Hills.

She later enrolled at the Promises centre in Malibu after her May 26 arrest for drink-driving and drug possession.
