Jocelyn Kirsch, one half of Philly's notorious identity-theft love duo, could lose her freedom today at a federal hearing prompted by her alleged criminal behavior while out on bail in California.

Kirsch is expected in federal court in Philadelphia for a detention and formal arraignment before U.S. District Judge Eduardo Robreno at 2 p.m.

A plea hearing at which the former Drexel University senior was expected to plead guilty to federal charges has been postponed, the U.S. Attorney's Office announced last night.

The other half of the so-called "Bonnie and Clyde" crime duo, Kirsch's ex-boyfriend Edward Anderton, was in Robreno's court on Monday and pleaded guilty to charges of conspiracy, aggravated identity theft, bank fraud, money laundering and other crimes. Anderton, now an Everett, Wash., landscaper, faces a sentencing hearing on Aug. 29.

Kirsch, once slated to graduate June 14 from Drexel with a degree in international area studies, faces the same charges. But California authorities alerted federal prosecutors last week of a credit-card theft that Kirsch purportedly committed.

The Daily News confirmed this week that Kirsch is under investigation by the Moraga (Calif.) police for a credit-card theft that was reported on April 17. It is unknown when or where the alleged credit-card transaction took place. Kirsch has not been arrested in the case.

An investigator in Moraga, north of Oakland, who did not want to be named, declined to give further details, saying that the case was under investigation. If her $50,000 bail is revoked, then the former Starbucks barista would fail to make her Monday court appearance in San Rafael, Calif. There, the Marin County District Attorney's Office has charged her with one misdemeanor count of filing a false emergency report, in connection with a 9-1-1 call involving the home she had moved out of some days prior. She lived there with her mother and stepfather.

Her Beverly Hills-based attorney, Stephen Kahn, has said that she would be in court and would plead not guilty. He did not return a call from the Daily News last night. *
