Lindsay Lohan house arrestAlthough it wouldn't surprise us if Lindsay Lohan was testing her house arrest boundaries, the locked down actress' ankle monitoring bracelet went off due to a fluke with the equipment. Lohan's ankle bracelet sounded an alarm on Monday, prompting authorities, who believed Lohan had left her specified premises, to arrive at her Venice, California home, according to TMZ.

But upon their arrival, probation officers found a casual Lohan tanning and reading scripts on her roof. A source told TMZ that the device may have "missed a signal" prompting the monitoring bracelet to give off a false alarm. Lohan was then fitted with a new device.
