No. Keanu was in a serious relationship with fellow actress Jennifer Syme in the late '90s and the couple was even expecting a child together, but their daughter was still-born. Shortly after, the couple split and Jennifer died in a car accident in 2000. He was reportedly married to Winona Ryder on the set of The Guardian, but that doesn't count. However, that doesn't mean he doesn't want kids (or a wife) in the future.
"I’d like to have a family. I’m getting older and maybe that experience can help you to be the best that you can be to yourself and to another person that you’re with,” he told Parade magazine in 2008. "I think you have to use communication and imagination in a relationship. It’s an imaginative act; it’s an act of creation."
Today, Keanu dates artist Alexandra Grant. The two took their relationship public in 2019, though it's rumored they began dating a few months prior.
