They both posted the happy news on Instagram on Monday.
“He took me to France and made a picnic and made me feel happy and free and then he asked me to marry him and i screamed YES. I love you @benshattuck_art, you are the kindest and brightest and I am so grateful and here we go and keep going,” said Slate, 37.
Shattuck posted his own announcement, writing, “In an abandoned castle in southern France, I asked this woman to marry me. Here she is in front of a door the color of her soul,” Shattuck wrote on his Instagram. “In LA / MA / Holland / Belgium / France thank you @jennyslate and UP UP UP to more adventures.”
The actress, best known for roles in “Venom,” “Parks and Recreation” and a stint on “Saturday Night Live,” also offered a peek at her engagement ring in the photos she shared.
Slate and Shattuck were first spotted getting cozy at the Sundance Film Festival in January.
Shattuck is also a writer and painter and works at the Dedee Shattuck Gallery in Westport, Massachusetts, which is owned by his mother.
