Keanu Reeves and Alexandra Grant appear to be a perfect match.

“This is the most fun and positive relationship that Keanu has ever been in,” a source tells PEOPLE, adding that Grant, an artist, “is a rare gem.”

“She is adorable, sweet, caring and funny. She has her own life and career but is also very supportive of Keanu’s,” adds the source. “When he films on location, she travels with him. When he films locally, she often visits the set.”

“Everyone just loves her. They live together and often have friends over for dinner. Keanu is very happy,” says the source.

Reeves and Grant went public with their romance in November 2019, making their red carpet debut at the LACMA Art + Film Gala presented by Gucci in Los Angeles at the time.

In September 2023, Grant told PEOPLE at the Los Angeles Beverly Arts Icon Awards that she feels “interdependent and independent in the best ways.”

She explained, “The good news about falling in love as an adult is that I had built my own career by the time that my relationship had begun. I feel very confident in the relationship on the red carpet. I feel confident on it alone.”

At the time, Grant also said Reeves, 59, is “such an inspiration to me,” adding that he is “so creative, he’s so kind. He works so hard.”

Grant’s friend, actress Jennifer Tilly, told Page Six back in February 2020 that the pair had been dating for much longer than fans realized. “I remember a couple of years ago, about a year and a half ago, [Grant] said, ‘Keanu Reeves is my boyfriend,’ and I’m like, ‘Wait. What? What? What?’ ” Tilly said at the time.

In March 2020, Grant addressed her romance with Reeves for the first time, telling Vogue about the attention she received after they went public.

“I think every single person I knew called me in the first week of November, and that’s fascinating,” she said at the time. “But the question I’ve been asking in all of this is: What is the opportunity for good?”

“Love at every level is deeply important to my identity,” the artist later added, also telling the outlet, “I deeply value the experience of being in relationships.”
