Her representative confirmed to American media on Sunday that Spears voluntarily checked into a treatment facility. The news comes several weeks after her arrest for driving under the influence in Ventura, California. Her court appearance related to the case is scheduled for May 4th. In recent weeks, she has been supported by her sons Sean Preston (20) and Jayden James (19). A source told Page Six that the singer was incredibly emotional during the arrest and felt ashamed and uncomfortable. "It has been a very tough few months," the source told Page Six. On March 4th, Spears was taken into custody after police stopped her for swerving while driving. During the arrest, an unknown substance was reportedly discovered in her car, and she is believed to have been under the influence of a cocktail of alcohol and drugs. She was released the following morning, according to the arrest record from the Ventura County Sheriff's Office. A spokesperson for the Ventura County District Attorney's Office stated to California Post: "The DUI case against Britney Spears has been submitted to the Ventura County District Attorney's Office, and our prosecutors are reviewing it."
