I wasn't wearing my glasses at first and I legit thought he was dating Helen Mirren which I also would have been here for. | Keanu Reeves, 55, goes public with his first girlfriend in DECADES https://t.co/Y5C2RV9kV1
Following their red carpet debut, an eyewitness told ET that the apparent couple was "smiling and having a good time" inside the LACMA Art + Film Gala in Los Angeles.
"Will Ferrell spotted Keanu and rushed over to say hello, bringing with him a small group that included his wife, Viveca Paulin-Ferrell," the eyewitness said. "It’s unclear if Ferrell and his wife already knew Alexandra or if Keanu introduced them, but they were seen chatting for several minutes before heading into the tented pavilion for dinner."
