Even while confined to her own house, it seems Lindsay Lohan can’t stay out of trouble.

Lohan is due back in Los Angeles court on Thursday, the AP reports, and TMZ is reporting that it’s due to a failed sobriety test. The troubled star was tested twice last week, the website writes, testing negative for drugs but positive for alcohol on one of the tests.

Lohan has been under house arrest — she recently filmed a commercial for Beezid.com from her home — and the L.A. County Probation Department will request that she be sent back to jail; she was assigned to wear an ankle bracelet in her home for 35 days, the end result of a four month sentence she received for violating the terms of her probation following a 2007 stint in jail, which she did by stealing a necklace from a Los Angeles jewelry store.

She had rejected plea deals earlier in the case, confident that she’d win.

“It’s a scary place and a place that I don’t wish on anyone,” she told Life & Style Magazine of her time in jail.

Blogger Perez Hilton confirmed with multiple sources that Lohan had failed one of two tests last week.

LOS ANGELES — Los Angeles prosecutors say Lindsay Lohan will return to court Thursday so a judge can consider whether she violated her probation while serving house arrest.

District Attorney’s spokeswoman Sandi Gibbons says Lohan’s case is expected to be called at 10 a.m., but no other details were available. She says her office has not received any documents laying out the specific allegations against the 24-year-old actress.

Lindsay Lohan is under house arrest right now, but that doesn’t mean she’s taking it easy. Lohan has just filmed a new commercial for auction site Beezid.com from her Venice condo, reports TMZ. At first Lohan was offered $25,000 for the gig and turned it down, but the company was able to entice her with an undisclosed amount and a $10,000 shopping credit for the site. Over $25,000 for an 18-second cut? That’s talent.

Lohan is serving 35 days under house arrest for pleading no contest to stealing a $2,500 necklace. She was originally sentenced to four months in jail but LA’s overcrowded detention centers and Lohan’s “nonviolent offender” status upgraded her holding pen to her own Venice condo, reports People.
