The Pint-Size Stars of ‘This Is Us’ Spill Secrets From the Hit NBC Show

Chances are if you love This Is Us, you also really love the adorable kids in the cast.

Entertainment Tonight caught up with the NBC breakout hit’s youngest stars Lonnie Chavis (9-year-old Randall), Parker Bates (9-year-old Kevin), Eris Baker (Randall and Beth’s oldest daughter, Tess) and Faithe Herman (Tess’s little sister, Annie) as they stepped out to support TV mom and grandma, Mandy Moore at the premiere of Disney’s animated television spin-off for Tangled.

The pint-size stars not only talk about their TV family and on-set shenanigans, but lucky for us spill a few secrets leading up to the season finale.

​

All four of the child actors were excited to see their This Is Us co-star come to life in the new Disney Channel show, premiering March 24. TV son, Bates even rocked a custom-made “Team Rapunzel” shirt.

“She’s, like, a really supportive TV mom,” he told ET. “She helps us with our lines and she rehearses with us. She’s a really good mom to have on set.”

“I can’t even describe how sweet she is,” Chavis said. “She’s just, like, a blossom that doesn’t care what nobody thinks.”

​

While Bates and Chavis were maturely diplomatic in revealing which of their adult co-stars they enjoy acting with the most, Herman and Baker shared their picks right away.

“Sterling [K. Brown] is so funny!” Baker shot up. “I love how he keeps on encouraging me, because if I mess up, he’ll be like, ‘Messing up is a part of life, you got this!’ … I fangirl every time.”

Herman agreed and said, “Sterling is really awesome. And Susan [Kelechi Brown], ’cause whenever we have breaks on set, they always have jokes and stuff and it’s really fun, and we talk to them. And then sometimes they play around on set.”

​

While all the kids have a very special relationship with their TV parents, Chavis admitted that he feels like he has a real-life father-son relationship with Pearson family patriarch, played by Milo Ventimiglia.

Not to mention, Chavis says the super-dramatic scenes are actually fun to watch while on-set.

​

Even though the show deals with grown up topics, all four kids say they’re allowed to watch full episodes — with exception to Baker and Herman, who say their moms ask them to “cover” their eyes during certain scenes.

Bates has no problem covering his eyes due to the awkwardness.

“Like, whenever [Ventimiglia and Moore are] kissing, I close my eyes, because I don’t like to see them kissing, ’cause I know them!” he said. “So, it’s kind of weird, and I know they’re not married in real life.”

​

In a form of monkey-see, monkey-do, Bates and Chavis say they learn a lot about acting from watching their older co-stars. However, the younger stars have the supplementary challenge of acting in a period they weren’t alive in, which makes for some pretty funny discoveries on set.

“Yeah, some of our outfits, sometimes they’re, like, really crazy,” Bates noted. “And, like, the TV in [the house]? It’s so little, and it’s like a box. And ours right now are flat screens.”

​

With just one episode left this season of This Is Us, it’s only natural we all want to get answers to how it’s going to end, especially when it comes to the passing of Jack.

“You can expect a lot more drama,” Chavis said. “And a lot more impact and action coming.”
