Dad jokes aside, it shouldn't come as a surprise that Facinelli still holds his Twilight character, Dr. Carlisle Cullen, close to his heart.

In September 2020, the Vanished actor – who wrote, directed, and starred in the thriller – opened up to PEOPLE about the possibility of reprising his iconic role as the patriarch of the Cullen family, saying he would do it "in a heartbeat."

"I love that character," Facinelli said at the time. "[He's] so much fun to play and that world is so fun."

Harrison and Facinelli, who have been an item since September 2016, got engaged on New Year's Eve in 2019 while vacationing in Mazatlan, Mexico.

The actor proposed while the couple was at a romantic beach dinner at the Estrella Del Mar Beach and Golf Resort. They were joined by Facinelli's daughters – Luca, 24, Lola, 19, and Fiona, 15, all of whom he shares with ex Jennie Garth — as well as Harrison's parents for the exciting celebration.

"Both are beyond elated and are very much looking forward to all that the New Year will bring," Facinelli's rep told PEOPLE at the time.

While speaking with PEOPLE in October last year, the Supergirl actor explained that he and Harrison aren't in a hurry to walk down the aisle – especially amid the ongoing coronavirus pandemic.

"I want [our wedding] to be in a world where there's no masks," said Facinelli. "There's no rush for us. We're devoted to each other and we're living a life together."

Even though the actor hopes their nuptials will happen sometime this year, "I already feel married," he told PEOPLE. "We have everything besides the piece of paper and the party!"
