An arrest warrant has been issued for Lindsay Lohan in her 2007 DUI case — though her lawyer claims it's all a big "misunderstanding."

"[A] warrant was in fact issued [March 13] for the arrest of Lindsay Lohan," says a statement from the Beverly Hills Police Department, obtained by "The $50,000 warrant issued by the Beverly Hills Superior Court stems from a May 2007 arrest of Miss Lohan for DUI and hit-and-run."

In that case, Lohan drove her Mercedes into a curb, with two passengers inside. Cited for DUI, Lohan entered the Promises rehab facility for six weeks. In July of that year, Lohan was pinched for another DUI. After pleading guilty to two counts of being under the influence of cocaine and pleading no contest to DUI and reckless driving charges, Lohan ultimately (and famously) served 84 minutes in jail.

What is the nature of this new arrest warrant? "The circumstances leading to the issuance of the warrant by the court are not readily available at this time," says the BHPD. "It is our hope that Miss Lohan will surrender herself so that this matter will be resolved in a timely manner."

Lohan's attorney, Shawn Chapman Holley, claims the warrant was "born out of a misunderstanding which I am confident I can clear up next week." As he tells Extra, "Since her case was resolved, Ms. Lohan has been in compliance with all the terms and conditions of her probation and all orders of the Court."

A rep for Lohan did not immediately respond to seeking comment on Saturday.
