The One has found a new reality. Just as ''The Matrix Reloaded'' was rakin' it in at the box office, Keanu Reeves acquired a trophy estate in Hollywood Hills' Bird Streets, home to Jennifer Aniston and Leonardo DiCaprio. Built in 1988, the 5,600-square-foot gated abode has glass walls with ocean and city views, stone floors, state-of-the-art security, and an infinity pool. No word whether Reeves will buy another house to celebrate November's ''Matrix Revolutions.''
