New couple alert! Halle Berry has joined the cast of John Wick: Chapter 3, and Life & Style has learned she's become much more than just Keanu Reeves' co-star. "Halle and Keanu are dating," an insider recently told the magazine, on newsstands now. "They started seeing each other even before they began filming. As soon as they started getting to know each other, they realized there was something there that was stronger than a friendship."

Their movie is filming in NYC, but they won't be showing any PDA between takes. "They want to keep their romance on the down-low for now," the insider told Life & Style. "But it's only a matter of time until they go public."

After her 2016 divorce from Olivier Martinez, Halle, 51, dated 35-year-old music producer Alex Da Kid for five months. But with Keanu, 53, she's found someone she thinks has long-term potential.

"Keanu is totally Halle's type," the insider revealed. "She likes that he's very mysterious, introspective, and down-to-earth. He's not about the whole Hollywood spotlight thing. She finds that very attractive — and, of course, she thinks he's super handsome."
