Keanu Reeves and Alexandra Grant are the internet's favorite couple. Here's a complete timeline of their relationship.

The artist revealed in a 2020 interview with Vanity Fair that her closeness with Reeves began after she gifted him the book over a decade ago.

"The book was made as a surprise, by me, for Keanu, as a private gift. All our friends sitting in the room got the giggles when I gave it to him — they said, 'Please publish it!' So that's how we got into publishing," Grant explained in the 2020 interview.

According to Vanity Fair, "Ode to Happiness" is "a playful guide to climbing out of depression" that combines text by Reeves with drawings by Grant. They later followed it up with a sequel, called "Shadows."

As Grant revealed, she and Reeves were inspired by their collaboration to open a publishing house (X Artists' Books) together, and subsequently grew closer.

The duo made an appearance together at the gala, but the actual nature of their relationship remained largely unknown to the public.

Grant and Reeves turned heads in matching all-black ensembles, and even held hands while posing for photos in front of the open ocean.

The couple walked the red carpet together at the LACMA Art and Film Gala, and the internet immediately exploded with speculation about Grant's identity, and joy for Reeves, who'd had a rocky romantic history before being linked to Grant.

Sources told ET that during the event, the two enjoyed catching up with friends — including Will Ferrell and Viveca Paulin, his wife — during cocktail hour and that Grant asked a friend to take a photo of her and Reeves on her phone.

In the interview with Vogue, Grant spoke about the public's reaction to her relationship with Reeves and how she was dealing with the newfound fame.

"I think every single person I knew called me in the first week of November, and that's fascinating," she told Vogue. "But the question I've been asking in all of this is: 'What is the opportunity for good?'"

The artist also spoke about her decision to keep her hair naturally gray, her upcoming work, and her thoughts on love and marriage.

"Love at every level is deeply important to my identity... I do not believe that isolation is the way," Grant said. "There is a period of isolation that I do as a painter, but I deeply value the experience of being in relationships."

Grant wore a form-fitting red dress, while the "Matrix" star kept it classy in a dark blue suit. The couple looked very much in love while on the red carpet, and held hands while posing for several photos.
