The 'Modern Family' star also opens up to ET about her singing aspirations.
Sarah Hyland says there's a simple reason why she and Wells Adams are so good together.
The Modern Family star attended 102.7 KIIS FM's Jingle Ball 2017 in Inglewood, California, on Friday, and raved to ET's Katie Krause about her new romance and how she and the former Bachelor Nation star are inspiring serious relationship goals.
"The whole relationship goals thing, I feel like that is said about a lot of people, a lot of different relationships," she confessed before adding, "He's the greatest."
Hyland celebrated her 27th birthday last month and gushed over how special Adams made her big day and the entire week. "Going in a helicopter, I was like, 'What!?'" she recalled before talking about their Disneyland excursion. "[Disney's] Club 33 was probably my favorite because ...I like [to] dress up really fancy and he was wearing a suit and looked dashing."
As for why she and Adams are so compatible, Hyland quipped, "We're the same person with different genitalia."
In addition to acting, Hyland has some impressive singing skills and shared what it would take for fans to see her perform at Jingle Ball one day. "You know what I want to do for Jingle Ball, let's put this out in the universe," she began. "I want to get three of my girlfriends ...and do 'Jingle Bell Rock' [dance] from Mean Girls. ...That needs to happen."
In the meantime, Hyland is trying to figure out how to introduce Adams to her Modern Family co-stars.
"These people have become my real-life family. It's almost like, you gotta," she told ET in an earlier interview. "Like, for guys, you have to meet the parents, which is stressful, but then I think the more stressful thing is to meet the second family -- which is not only the Dunphy family but the entire cast, the entire crew and all of our writers, and everybody that's involved. That's the second family that I think is the most terrifying thing for guys that I date."
