Keanu Reeves' Hollywood Hills home - which has been described as being 'built like a fort' - has been broken into twice in one week.

Earlier this month, Reeves found a woman in his library. Two days later, the actor was alerted to a woman swimming naked in his pool.

According to TMZ, police officers first responded to reports of a burglary at Reeves' home on September 12.

Reeves, 50, was asleep until he heard noises coming from the library. Around 4am, the sounds led the Matrix actor to a woman sitting in his library chair.
