EXCLUSIVE: Lindsay Lohan Not Allowed Visitors This Weekend

It's going to be a lonely weekend behind bars for Lindsay Lohan. Family and friends will not be allowed to visit the Mean Girls star this weekend, RadarOnline.com is reporting.

Lindsay will be spending her first weekend in jail without visits from friends or family because she used her allotted visits during the week.

"Inmates are allowed two 30 minute visits a week, from family and friends. Those don't include professional visits by attorneys. Ms. Lohan already has had her two thirty minute visits for the week," Los Angeles County Sheriff's Department spokesperson, Steve Whitmore told RadarOnline.com.

Lindsay was visited by mom, Dina, and little sister Ali earlier this week, and ex-girlfriend Samantha Ronson visited her Thursday.

Other inmates are allowed visitors only on weekends.

So why the special treatment for Lindsay?

Security reasons, says Whitmore. "Ms. Lohan was allowed the visits during the week for security reasons," Whitmore told RadarOnline.com. Lohan is scheduled to be released in very early August, but as RadarOnline.com reported Thursday Lohan could get credit for time served when she was previously in custody.
