The This Is Us star, 44, and Pernas, 31, made their first red carpet appearance as a couple on Sunday night during the 2021 MTV Movie & TV Awards, hosted by Leslie Jones.
Both could be seen wearing rings on their wedding fingers as they posed on the carpet together. They first sparked speculation about their relationship status when they were photographed wearing rings earlier this month.
A source confirmed to PEOPLE last June that Hartley and Pernas had been dating “for several weeks.” Later that year, the actors made their relationship Instagram official on New Year’s Eve.
“Sayonara 2020, it’s been real. Happy New Year from our quarantine den to yours,” Pernas wrote on Instagram at the time, sharing a selfie of the couple.
On his Instagram page, Hartley shared a black-and-white photo of the duo smiling and dressed up for the occasion. “Last minutes of 2020 here in LA. Bring on 2021! Happy New Year!” he wrote.
