Many thanks to Nina for sending in the news.
Keanu came up on the radar screen yesterday, December 30. He was sighted leaving Spago in Beverly Hills after having dinner with friends. It is clear from the video clip that the small group of people waving to him in the background were with him. He left in a light colored vehicle and that was driven by one of his friends (male).
All of the photos can be viewed here.
Update: The video clip of Keanu leaving Spago can be seen at youtube. The same sighting has also been reported at JustJared.
Note: The youtube video, which was posted by KeanuWorld, has been removed by youtube. Apparently KeanuWorld has had their account nuked by youtube for repeated third party content copyright issues – no surprise there!
