Many thanks to itsmeara for sharing a photo of Keanu on webstagram and to @keanulatino for tweeting the instagram version.
The photo is from the back but it definitely looks like Keanu. It was posted at 14:38 today and was taken at some campus. Those are the only details given so that’s all I got. If you are interested to know more, then go and ask the poster on webstagram.
Note: The photo poster is a UX Engnineer at Media Temple which is a web hosting company. UX engineers design products that are at the user interface. There are no companies by that name that is associated with any kind of film production tha shows up on google. I find it hard to believe that Keanu visited a web hosting company for starters. I also find it odd that a company would refer to their work environment as a campus.
