This is scary!

A man broke in to Sandra Bullock's Hollywood home early on Sunday morning, and not only was she present at the time of the incident, but a police spokesperson reveals that the intruder may have been stalking the Oscar winner!

Bullock attended the Guys' Choice Awards on Saturday night and stopped by an after party in West Hollywood, and around 6:30am on Sunday police arrested 39-year-old Joshua Corbett on suspicion of residential burglary.

"An intruder was arrested on [her] property this morning," Bullock's rep said in a statement. "She is unharmed and is fine." Law enforcement sources tell Today that Corbett "might have even kept a diary devoted to Bullock." Creepy!
