In September, Grant gushed about how Reeves inspires her creatively during an appearance at the Los Angeles Beverly Arts Icon Awards. "He's so creative, he's so kind. He works so hard," she told People magazine at the time.

The mixed-media artist also shared how her relationship with Reeves has affected her career, noting that a friend told her years ago that her "work has gotten happier."

"That's real. We're all human beings. We're animals," Grant said. "We're expressing from where we are and certainly feeling happier. I think the work is happier."
