Britney Spears has entered rehab following her arrest on suspicion of driving under the influence.

The 44-year-old popstar "has voluntarily checked herself into a treatment facility," a representative for Spears confirmed to USA TODAY on April 12.

The news was first reported by the Celebrity Intelligence newsletter.

The move comes a month after she was arrested March 4 outside of Los Angeles County. A California Highway Patrol spokesperson told USA TODAY on March 6 that Spears was suspected of driving under the influence of alcohol and drugs, as she allegedly showed "signs of impairment and submitted to a series of field sobriety tests."

Spears was driving a black BMW 430i "erratically" at high speeds on the highway in Ventura County, according to the CHP. She is due for a court appearance on May 4.
