If it wasn't creepy enough that someone broke into Sandra Bullock's home while she was sleeping on Sunday morning, try this on for size: The guy had reportedly been keeping a diary about Bullock as part of an ongoing obsession with the actress. Police sources tell Today (via E!) that the suspect, Joshua Corbett, may have been tracking Bullock before he finally trespassed on her property. According to the report, he may have also gone through some of her personal belongings before cops arrived just four minutes after he allegedly got inside. As of Monday morning, Corbett was reportedly being held in the custody of police, who may add to the residential burglary charge with which he was initially booked.
