Keanu Reeves is being supported by his girlfriend, Alexandra Grant.

The Los Angeles-based artist was recently spotted kissing and laughing with Reeves, 59, on the set of his upcoming film Good Fortune.

Although the comedy film was announced in April 2023, its premise remains under wraps. Seth Rogen, Keke Palmer and Aziz Ansari, who is also the project’s writer and director, star with Reeves.

Palmer, 30, hinted at what fans can expect from the film in January, stating in an Instagram post that there was “a pool scene today that lowkey turned into a real pool party.”

It’s no surprise that Grant was spotted on the movie set, as a source told PEOPLE, “This is the most fun and positive relationship that Keanu has ever been in.”

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

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

Reeves has certainly been busy as he is also filming Outcome, alongside Jonah Hill.

In Outcome, Reeves will play a “damaged Hollywood star” named Reef, “who must dive into the dark depths of his past to confront his demons and make amends after he is extorted with a mysterious video clip from his past.”

The movie star is also set to make waves in the literary world, as he announced in January that he and author China Miéville collaborated on the novel titled The Book of Elsewhere, inspired by his comic book series BRZRKR.

“The series tells the story of an immortal warrior’s fight through the ages, and I love the world of BRZRKR so much that I wanted to explore it further and I thought one of the best ways to do that is through a novel,” Reeves said during an appearance on Good Morning America.

The novel will be out on July 23.
