Pernas also posted a photo on her Instagram, saying "sayonara" to a trying year.
The 31-year-old actress, who previously worked together with Hartley on The Young and the Restless, wrote in the caption, "Sayonara 2020, it’s been real. Happy New Year from our quarantine den to yours."
A source told ET at the time that Hartley and Pernas "are newly dating and are enjoying their time together. The couple has spent time together during quarantine and has taken the time to get to know one another better, as they have worked together in the past but weren’t romantic."
Their new romance comes amid Hartley's divorce from Chrishell Stause, the aftermath of which was shown on Selling Sunset. The source added in May that "Chrishell is upset because they only split at the end of 2019, but she understands they both need to move on."
“I feel like anybody would be heartbroken to see how quickly or easily you are replaced; of course that’s going to sting,” Stause told People magazine. “I’ve had to start over so many times in my life,” she tells the publication. “I always know how to look at the bright side because there’s been a lot of dark.”
