The couple were first married in 2005 and split in 2012. The two reconciled last year.
The pair is set to make their debut as an engaged couple at Saturday's Make-Up & Hair Stylists Guild Awards where Embry, 36, will be presenting, reported People magazine.
"I finally put the ring back where it belongs," said Embry, 36, who will star alongside Lily Tomlin and Jane Fonda in Netflix's upcoming comedy 'Grace and Frankie'.
"I am very happy and so grateful we found our way back to each other!" Mabrey, 39, said.
