OK, which one of you has been calling Lohan in the chokey?

Thousands of Lindsay Lohan’s fans are calling in their support — literally — as the Freaky Friday actress buckles down for her second weekend behind bars.

Obsessed Lohan fans have been calling the jail where the actress is serving a 90-day sentence by the hundreds in desperate attempts to speak to the fallen starlet, cellblock spies spill to TMZ.com. We hear the Century Regional Correctional Facility in suburban Los Angeles has been receiving up to 100 calls an hour since Lohan turned herself this month on charges of violating the terms of her 2007 probation.

Although hardnosed DUI judge Marsh Revel initially sentenced LiLo to 90 days in the clink, the actress will likely be released much sooner, thanks to overcrowding in the California prison system.
