When asked by host Jimmy Fallon if he always knew that he and Turner-Smith, 34, were “destined” to get married, Jackson said, “I knew the moment she asked me.”
“She asked me, yeah, on New Year’s Eve,” the Dawsons Creek alum continued. “We were in Nicaragua. It was very beautiful, incredibly romantic. We were walking down the beach, and she asked me to marry her.”
As Fallon then questioned Jackson whether Turner-Smith’s proposal was planned, the Dr. Death star responded, “There was like a preamble. There was a lead-up to it. I did not know [about it beforehand], but she was quite adamant, and she was right. This is the best choice I ever made.”
PEOPLE previously confirmed that Jackson and Turner-Smith tied the knot in 2019. The Affair actor and Turner-Smith first sparked romance rumors after being spotted together grabbing lunch — and holding hands — in November 2018.
In August 2019, the actress then made their relationship Instagram official, shortly before the pair made their red carpet debut as a couple while attending the premiere of Turner-Smith’s film Queen & Slim.
