The "That 70's Show" alum is engaged to his girlfriend of one year, Ashley Hinshaw.
The duo attended the Art of Elysium Heaven Gala in Santa Monica together on Saturday, where the actress showed off her new sparkler for the first time on the red carpet.
Hinshaw has appeared on "True Blood" and "Agent Carter," and will pop up on the highly-anticipated second season of HBO's "True Detective."
The actor had a lot to celebrate over Golden Globes weekend ... including a reunion with his "70's Show" costar, Laura Prepon.
The former on-screen flames posed for pictures together at the pre-Globes bash. Check out more party pics from the weekend above!
