For their first public outing as a couple, Keanu took Alexandra to the LACMA Art + Film Gala, presented by Gucci, in Los Angeles on Saturday night.

Keanu and Alexandra collaborated on a book, Ode to Happiness, in 2011 after reportedly meeting in 2009. They grew increasingly close over the years - even as Keanu dated other women including actresses Charlize Theron, 44, and Halle Berry, 53 (below).

Keanu and Alexandra wrote their 2nd book together, Shadows, in 2016, according to Dailymail.com. An artist, poet, journalist and photographer, Alexandra photographed Keanu on the set of his popular assassin film series John Wick.

She also photographed Keanu on the set of The Matrix. She said she was in awe of the way he moved, and she included those photos in their book, Shadows.

"No one can move the way he can. He's a really extreme performer. That's a huge piece of why those images are so interesting,” she told W. "I knew that if I moved the camera as we danced together, as photographer and subject, we could create these wonderful optical illusions."

She told W magazine that their differences make them compatible.

"We can spend a lot of time debating. Like, 'A raspberry hue? And should it be darker?' We can get obsessive."

Keanu made his star turn in the drug culture comedy flick Bill & Ted's Excellent Adventure in 1989.

Last year, I told you that Halle Berry and Keanu Reeves were reportedly dating. The couple's reps denied they were a romantic item. Today, they took their relationship public at Keanu's Hand And Foot Print Ceremony at the TCL Chinese Theatre IMAX in Hollywood.
