Many thanks to Dr. Beardsley for sharing his selfie with Keanu Reeves on his FB page and to @LavenderFlo for the heads up. The photo was posted about 3 hr ago and was taken yesterday, Feb 20. From another photo and comment, Dr. Beardsley attended the pre- Oscar party at the Los Angeles British Consulate on Friday, February 20. He is wearing the same tux in his photo with Keanu that he wore to the pre-Oscar party.
Update: Dr. Beardsley has updated his post. He added a photo from the time he met Keanu back stage at a James Brown concert at the House of Blues several years ago. You can view it here.
