When asked about Clarkson's recent confession that she wants her 3-year-old son, Remington, "to marry [3-year-old] Luna," the Lip Sync Battle co-host gushed right back.
"She has the most incredible family," Teigen, 33, told ET's Ben Aaron at the NBC Upfront. "Our kids and her kids hang out backstage at The Voice, and River is just such a little... she, like, runs my daughter. She's like, 'Here's what you need to do.' She's, like, taken over backstage because she's been there longer, and it's adorable to see."
"Imagine that wedding. Imagine John [Legend] and Kelly Clarkson singing," Aaron responded, to which Teigen said, "I'd be thrilled. I'd be thrilled."
The Voice coach recently told ET about her future dreams for their kids.
"My little boy, I told Chrissy, I want to marry Luna," Clarkson shared. "They would make the most beautiful babies. Their skin tones, their eye color, I'm like, 'What would that baby look like?' They probably think I'm weird. Definitely they probably think I'm weird."
The 37-year-old singer added that the pint-sized pair would also make a solid match due to their shared background growing up in Hollywood.
"I think it's fun to have other kids that kinda grow up in an environment... it's not normal. You know, it's not like an everyday scenario, like how we all grew up," she said. "So I like that they at least get people to hang out with every once in a while... with the same kinda vibe to where they don't feel weird."
While Clarkson and Legend keep busy coaching singing hopefuls on The Voice, Teigen is gearing up to judge NBC's Bring the Funny comedy competition series, set to premiere on July 9.
"It's this incredible show where we get to showcase all different broad forms of comedy," she told ET. "We just sit there, and we laugh all day. That's the gig. It's sit there, laugh, critique people, and that's my dream."
