The This Is Us star opens up about her newfound love

‘Tis the season for love!

This Is Us star Chrissy Metz couldn’t help but gush about her new beau at KIIS FM’s Jingle Ball 2016 at Staples Center in Los Angeles on Friday.

“He’s not an actor, but he is a sweet treat and he’s wonderful,” Metz told Entertainment Tonight at the iHeart Radio-sponsored event. “It’s new, but I will be kissing him under the mistletoe.”

Metz, who hinted that the four-month-long relationship is getting serious, previously opened up to PEOPLE about her secret to finding love.

“No matter what size I’ve been, I’ve never had issues dating,” she said. “I’ve found really wonderful men, and I do believe that like attracts like. It’s one of those things where if you’re secure and you’re happy mostly, you find really wonderful people who come into your life.”

Though the 37-year-old, who remained hush-hush on disclosing the identity of her lucky guy, previously told PEOPLE that the relationship blossomed naturally.

“It wasn’t like they came out of the woodworks just because I’m on the show,” she says. “It was just organic, and I’m grateful for that because I know it’s difficult to be dating and in the spotlight and having things change.”

Speaking of being in the spotlight, Metz revealed why she’s determined to keep her newfound love on the down-low.

“Here’s the thing, like, he needs to have his own life,” she told ET. “I don’t want him roped into mine, so I just want to protect him. My little sweet treat.”

Despite keeping the major details to herself, Metz did let us all in on one little secret.

When asked if she was in love, the actress responded, “You know what? I think I am,” and added, “It’s such a blessing — really it is. It really is.”
