Lindsay Lohan still hasn't selected a rehab clinic.
The 'Liz & Dick' star - who was sentenced to 90 days in treatment after pleading "no contest" to charges for lying to police about driving during a car crash on the Pacific Coast Highway in California last June - must enter a facility on Thursday or she will have to appear in court for violating her probation.
A source told E! News that the 26-year-old actress still hasn't made a decision about where she will seek treatment and time is running out for her to "secure admission into a court-approved facility."
The insider said Lindsay will be "required to show up to court on Thursday with her lawyer Mark Heller in Los Angeles," if she hasn't registered for a program on or before Thursday, adding: "If Lohan does not comply with the judge's order that would be a violation of probation that could land her in jail."
Lindsay, who has been looking at rehab clinics in New York, was previously said to be in discussions with website Celebuzz recently to detail her experience for their readers and is due to meet with editors to discuss ideas.
Celebuzz consultant A.J. Daulerio recently said: "I'm still waiting for the official grooming session (with Lindsay)."
If both parties can agree terms the 'Scary Movie 5' star's first rehab diary post would happen in August after she checks out.
An insider said: "She will not be blogging from rehab but she does plan to have her own space on the web where she can talk about her passions. She wants a place to discuss her love of fashion, music, art and her unique sense of style. She wants to be able to connect to her fans directly."
