Chrissy Metz
was overcome with emotion when she found out she scored her first Golden Globe nomination on Monday, alongside her This Is Us co-star, Mandy Moore.

“I love Mandy so much, I really do, and if I can be in a category with her and all the other women, come on!” an “elated” Metz told ET’s Carly Steel on the set of This Is Us of her Best Supporting TV Actress nomination. “We literally were crying in each other’s arms, just really happy for each other.”

The 36-year-old actress struggled to find the words to describe the feeling of being a Golden Globe nominee. “You’re elated, you’re excited, you’re beside yourself,” Metz said. “I’m all of those wrapped into one because it’s been a long time coming. I’m just feeling all the good stuff.”

Metz, who plays Kate Pearson on This Is Us, reflected on how her perspective on her character has changed since she stepped into her shoes in the pilot.

“It takes me back to a time when I was insecure and I really cared about what people thought, so I’m glad I can pull from real-life experiences because now I don’t really care what people think,” she said. “It made me appreciate where I’ve come from and what I contended with and really dealt with, and I think that translates and that’s why people are so moved by all of our performances.”

For Metz, whose character is considering gastric bypass surgery to lose weight, getting acknowledgement for this role holds a significantly different meaning to previous parts she’s played.

“It’s beyond words. I was entrusted with a really great role and I feel very honored to have been given that because not everybody gets that, and I hope I’m doing it justice,” she said. “It’s what you’ve always wanted as an actor, and as a human being, to relate to each other.”

Metz also spoke of growing up as the “biggest girl” in school and that everyone -- no matter their clothing size -- has insecurities.

“I was the biggest girl in my [high school] and that point, I was probably a 10 or a 12, and you kind of compare and despair, like ‘Dang, if I was a size 12 now I’d be like dang! That’s a great size,’” she recalled. “We’re always nitpicking ourselves. This role lends a lot of vulnerability, and then you realize that no matter what you’re contending with, we can all relate to feeling inadequate and how it’s not even real because we’re all pretty amazing just the way we are.”

“Who wants everyone to look alike and be the same because that’s boring?” Metz asked. “It’s art imitating life and it’s pretty amazing.”

As for what Metz will wear to the big night, she admitted she hasn’t even thought about her Golden Globes gown.

“It’s actually not the first thing on my mind,” Metz said. “And I think it’s because I hadn’t ever identified with my body or who I’m wearing, but with who I am as a person. I’m like, ‘Oh yeah, I gotta find a cute dress!’ But there’s been a couple designers reaching out to me, which is so nice, because six months ago, they were like, ‘Chrissy who?!’”

“For me, I want to look cool and comfortable and I want to feel good,” she explained.

Sterling K. Brown,
who is nominated for his turn as Christopher Darden in The People v. O.J. Simpson: American Crime Story, praised his co-stars -- notably Moore and Metz -- for their peerless work. “To see that my castmates have been recognized in such a wonderful way, Chrissy Metz and Mandy Moore, I'm over the moon,” Brown told ET on the This Is Us set. “The show getting its rep, and then the O.J. train has just been chugging and chugging along.”

What was Brown up to when nominations started rolling in early this morning? We’ll let the actor share in his own words! “I was probably just getting out of the shower. And as I was moisturizing myself because I'm African American and I try to take care of my skin, the phone started buzzing,” he hilariously recalled, adding his mom and family in St. Louis, Missouri, have been texting him all morning. “A lot of love coming my way.”

The Golden Globes, hosted by Jimmy Fallon, airs live coast-to-coast on Sunday, Jan. 8 at 5 p.m. PT/8 p.m. ET on NBC.
