It's safe to say Keanu Reeves is cool under pressure.
ET can confirm that a woman was detained at Reeves' home in Hollywood around 5 a.m. Friday, September 12, and was taken to a medical facility for psychiatric evaluation.
But it's what reportedly happened before she was detained that proves Keanu is pretty great at keeping his cool.

According to TMZ, Reeves woke up when he heard sounds coming from his library at around 4 a.m., and when he went to check it out, saw a woman sitting in his chair. It was then that the 50-year-old actor reportedly calmly approached her and began speaking to her. After she explained she was there to meet him, he then "very calmly" proceeded to call 911.
A trespassing report was taken, and the investigation is currently ongoing.
