Judge Antonio Barreto Jr. informed Sizemore that his "drug use is out of control" and ordered him jailed. His bail was set at $25,000.

"I had hoped and wanted to see a positive performance," Barreto said.

Sizemore had been granted permission by the judge to leave for Cambodia next week to shoot a movie, but only if he submitted to daily drug testing.

Sizemore's attorney, Michael Rovell, told the Associated Press that the temperature of the Feb. 1 sample provided by Sizemore indicated that it was too low to have come from his body and that the Black Hawk Down star was accused of concealing a supply of clean urine on his person.

Los Angeles Deputy City Attorney Robert Cha told Celebrity Justice that authorities had recovered from Sizemore a prosthetic penis attached to a pair of men's underwear holding a container filled with clean urine.

The device, sold on the Internet under the name "The Whizzinator," is often used to try and falsify drug test results. It retails for $150 and comes complete with dehydrated urine and heat packs designed to keep the sample at the proper temperature.

Cha said that Sizemore has been caught using the mechanism once before and has failed drug tests on numerous occasions.

Rovell said that Sizemore had denied cheating on the test and had offered to be tested again and had even passed a lie-detector test on the matter.

According to Celebrity Justice, Sizemore told the court that he is destitute and living in a garage in Whittier, California. He also reportedly claimed that he was an expectant father.

However, Rovell told the Associated Press that Sizemore is currently ensconced in a sober living facility in Whittier. He did not comment on the thesp's alleged impending fatherhood.

Rovell said he expected bond to be posted Friday and that Sizemore would be released.

Sizemore was sentenced to six months in jail in October 2003 for hitting and harassing Fleiss. So far, he has managed to avoid doing the time, but it's unclear how much longer he can keep himself out of the big house.

In August, Sizemore was arrested at his West Hollywood home after police allegedly found a controlled substance while conducting a random search of the property. In May, the actor tested positive for methamphetamine during a drug test.

Most recently, Sizemore was sued by a woman who claims he sexually harassed her while filming the now-defunct CBS series Robbery Homicide Division.

The actor is due to return to court on Feb. 24.
