Could Lindsay Lohan be heading to jail? Get the latest details as they come out today on "Showbiz Tonight" 5 p.m. ET on HLN.

A Los Angeles judge revoked actress Lindsay Lohan's probation and issued a bench warrant for her arrest after she failed to appear at a hearing Thursday.

A judge ruled that there was "probable cause to believe (Lohan) is in violation of probation" from a 2007 drunk driving conviction.

Lohan lost her passport and was unable to fly back to the United States for the hearing, Lohan attorney Shawn Chapman Holley said.

Holley later said Lohan was issued a temporary passport by the U.S. Embassy in Paris, France, on Thursday and will fly back to the United States as soon as possible.

Judge Marsha Revel ruled there was "probable cause to believe (Lohan) is in violation of probation" from a 2007 drunk driving conviction.

When Lohan is arrested, she would be allowed to post a $100,000 bond until a probation revocation hearing can be held, Revel said.

Lohan cannot drink alcohol until the hearing and she will be fitted with a bracelet to detect if she has been drinking, the judge said.

Random drug testing also will be performed on the actress, because of previous evidence she was under the influence of cocaine, Revel said.

"I warned her before," the judge said. "She knew it was very serious."
