The couple were spotted wearing rings while making their red carpet debut at Sunday night’s MTV Movie and TV Awards.
Multiple entertainment publications confirmed that the This Is Us star and his 31-year-old former Young and the Restless castmate “recently” walked down the aisle.
Hartley, 44, first confirmed they were dating in a sweet New Year’s Eve message.
The actor was previously married to Selling Sunset star Chrishell Stause from 2017 until they split in 2019. Their divorce was finalized in February.

Their divorce was detailed on the third season of the hit Netflix reality show, and later again during Stause’s time on Dancing With The Stars.
Hartley’s first wife was his ex-Passions costar Lindsay Korman, who is the mother of their 16-year-old daughter Isabella. The pair was together for eight years.
ET has reached out to reps for Hartley and Pernas for comment.
