On Saturday, the Matrix Resurrections actor, 57, and his artist girlfriend, 49, attended the 2022 MOCA Gala held at the Geffen Contemporary at the Museum of Contemporary Art in Los Angeles.
They walked the red carpet together, holding hands and smiling into each other's eyes during the outing.
The couple went public with their romance in November 2019, making their red carpet debut at the LACMA Art + Film Gala presented by Gucci in L.A.
Reeves and Grant have been friends for years, and even collaborated on works together, such as Reeves' 2011 book Ode to Happiness and 2016's Shadows, which was also written by Reeves with illustrations by Grant.
In February 2020, Grant's friend, actress Jennifer Tilly, told Page Sixthat the couple 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, 63, said at the time.
Grant addressed her romance with Reeves for the first time in March 2020, opening up to Vogue about the attention she received once they went public with their relationship.
