The This Is Us star was also smokin' at the A Bad Moms Christmas premiere in a standout burgundy Valentino suit with a white button-up and black tie and shoes. The 40-year-old actor also added some major bling on his wrist, a classic 42.5mm stainless steel automatic timepiece by David Yurman worth $3,400.
Hartley, who recently tied the knot with longtime girlfriend Chrishell Stause, chatted with ET at the premiere about his honeymoon plans and married life.
"Oh, gosh. I like saying wife," Hartley exclaimed. "I like saying it. It's beautiful, I'm happy. I couldn't be happier."
