“We saw Carl at Sundance and I’m at the point now with Bravo stars where I think we’re friends,” Teigen, 38, explained on Thursday’s episode of SiriusXM’s “Andy Cohen Live.”

“I have never met Carl,” the model elaborated. “I’ve never spoken to him, but we saw each other at I think the Variety booth thing and, in my mind, he had a really complicated flight back to New York.”

Teigen clarified that Radke, 38, had a “Delta first-class direct” flight, but asked him to board their PJ nonetheless.

“I was like, ‘You should come with us,’” she added.

Radke readily agreed, but had an awkward interaction with Legend, 45, once it was time to board the aircraft, Teigen said.

“It was really funny actually because John was seated already and then Carl came on and John was still sitting, like, he didn’t pop up to give him a big hug or anything so Carl so graciously came over,” she recounted.

“[Carl] was like, ‘Hey man, I just want to say thank you so much. I love you.’ It was so sweet, and John was like, for a minute I could see John being a little …”

Host Andy Cohen asked Teigen if Legend became “jealous,” which she confirmed.

“He’s got the tight pants, and he looks great,” she said of the “Tonight” crooner’s reaction to Radke.

“[John’s] like, ‘Yeah. [Carl’s] sober and he’s just like a really wonderful personality like you said. He just seems like a fun, cool dude.’”

Teigen, a fervid fan of Bravo programming, noted that she had every intention of pressing Radke — who split from now-ex-fiancée Lindsay Hubbard in August — about any ongoing “Summer House” drama, but “passed out immediately” after takeoff.

“I had so many questions,” she lamented.

Elsewhere in the interview, Teigen confessed that she had her own issues with jealousy during the early stages of her romance with Legend.

The couple — who tied the knot in 2013 — shares daughter Luna, 7, son Miles, 5, daughter Esti, 12 months, and 7-month-old son Wren.

“Going to his shows when I was younger, like when we had first met, and he would pull up a girl for the slow dance and we would fight about this at the end of the night, like, I was so jealous and unhinged,” she told Cohen, 55, adding that one music video shoot was particularly tough for her.

“The ‘Green Light’ music video sticks out in my head,” she said.

“Poor Anthony Mandler. This was the director of it, and I was sitting there watching the monitor and he was just simply talking to a girl. It was a party scene and I got in my car, like wheels were going. I was like, I just wasn’t well.”

These days, Teigen said she “couldn’t care less” about Legend’s exchanges with female co-stars or fans.
