Keanu Reeves, 55, and his girlfriend Alexandra Grant, 46, have kept their longtime romance fairly low key — but were just spotted together in San Francisco! Alexandra appeared to be visiting Keanu while he shoots The Matrix 4 on Thursday, Feb. 22 marking the first time they’ve been seen since confirming the relationship. The couple were casual and relaxed as they exited the luxe Omni Hotel, located just steps from the city’s iconic waterfront and Union Square.
