LOS ANGELES – A judge sentenced Lindsay Lohan to 30 days in jail and warned the actress Wednesday that there would be plenty more time behind bars if she violated further court orders.

Superior Court Judge Stephanie Sautner imposed the complicated new sentence, telling Lohan she would have to serve more than 400 hours of community service at the county morgue, undergo counseling sessions and report to court frequently to avoid further jail time.

In all, Sautner sentenced Lohan to 300 days in jail for violating a court order, but said the actress would only serve the additional 270 days if there was another violation. In reality, however, the initial 30-day sentence will be significantly shortened by jail overcrowding, with Lohan likely serving only about six days. The actual length of the term will be set by the sheriff’s department, which oversees county lockups.

The actress has until Nov. 9 to report for her jail term, and Sautner ruled she cannot serve house arrest, as she did previously this year.

The judge is keeping a short leash on Lohan, ordering her to report to court for monthly updates between December and March. She said Lohan can no longer leave the country and would have a new “no-nonsense” probation officer.

The judge said the highly structured sentence was known in judicial circles as “putting the keys to the jail in the defendant’s hands.”

Lohan, 25, acknowledged violating her probation by being terminated from a community service assignment at a women’s shelter earlier this year and missing psychotherapy sessions that the judge previously ordered.

Wearing a polka-dotted dress, Lohan arrived at the courthouse about 10 minutes early and spoke only briefly in court, telling Sautner she understood the sentence and was OK with it.

Sautner noted that Lohan’s popularity in certain circles is low, saying another women’s shelter refused to accept her for a community service assignment because she was considered a bad example for the women.

Lohan’s previous probation officer also wanted off the case, and the new officer is under orders to report any violations directly to Sautner.

It will be Lohan’s fifth jail sentence since being arrested twice for drunken driving in 2007. She last served 35 days of house arrest on a four-month sentence.

Paternity claim against Bieber called ‘false’

LOS ANGELES – An allegation that Justin Bieber fathered a baby by a woman who has filed a paternity suit is “defamatory and demonstrably false,” a spokeswoman for the singer says.

Melissa Victor said Bieber’s camp will “vigorously pursue all available legal remedies” in response to the allegation.

Online court records show Mariah Yeater filed a paternity suit against Bieber, 17, on Monday in a San Diego court. Radar Online posted a copy of the lawsuit on its website.

Yeater, 20, said she had sex with Bieber after one of his concerts at the Staples Center in October 2010, according to the posted suit. She said she gave birth to a boy in July and believes the teen heartthrob is the father. She is asking a judge for child support and a paternity test.
