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.

Her spokesman Steve Honig says he could not comment on the hearing.

Lohan has been on house arrest since last month. She had been expected to serve 35 days of a four-month sentence for violating her probation on a 2007 drunken driving case by taking a necklace from a store without permission.

Lohan resolved the theft case with a no contest plea in May.
