On Sunday, the Twilight star, 29, posted photos of the couple at DAOU Vineyards in Paso Robles, Calif., where Dome flashed her custom oval-cut diamond engagement ring from Ring Concierge.

Lautner captioned the sweet snaps: "Cannot wait to spend forever with you @taydome You love me unconditionally. You don't put up with my 💩. You calm me when I'm anxious. You make me laugh way too much. You make every single day spent with you so special."

"And most importantly, you make me a better person. I can't thank you enough for what you've brought to my life. I love you forever," he concluded the loving post.
