As it turns out,Christopher Caldwell Kat Graham and Darren Genet's romance wasn't an immortal one.

One year after announcing their engagement, Kat and the producer have broken up, the Vampire Diaires alum shared July 12.

"After many years together, Darren and I have chosen to no longer be together," she wrote on her Instagram Stories. "The engagement ended a few months ago. He's a great guy and we wish each other noting but the most happy and beautiful life."

Although the duo largely kept their six-year relationship out of the public eye, they offered fans a rare look into their romance when they made their red carpet debut in December 2021, four years into dating. Later that month, Kat shared a peek into her holiday celebration with the Muse director.

"Merry Christmas everyone!!!!!" the 33-year-old captioned a shot of her kissing Darren, which has since been deleted. "Wishing you the most beautiful Christmas, Hanukkah, Kwanzaa! However you celebrate, we hope your days are filled with love and happiness."

By May of 2022 Darren popped the question to the actress while the two were vacationing in Mexico for his birthday.

And now, she's looking ahead and focused on her future projects.

"Super excited to announce my first book everrrrr," she wrote June 7 alongside a picture of herself posing next to her book. "Thank you @clarksonpotter @penguinrandomhouse for believing in me and giving me an opportunity to help guide, heal and grow thru the Seasons of You journal. Excited for everyone to discover themselves in a deeper, more loving, and more forgiving way."
