Camila Cabello and Lil Nas X get stuck in elevator before promoting new single "He Knows"

Camilla Cabello revealed she and Lil Nas X got stuck in her building's elevator “for a good hour.”.

Camila Cabello and Lil Nas X recently found themselves in a nightmare scenario.

In a new interview with Rolling Stone, Cabello revealed she and Lil Nas X recently got stuck in her building's elevator "for a good hour" while on their way to promote their new collaboration, "He Knows," at a gay nightclub in Los Angeles.

"Panic attacks were happening left and right, honey," the Fifth Harmony alum recalled of the moment, which occurred as they were leaving her home for a night out at Heart in West Hollywood. "People were dropping like flies emotionally, but me and Nas, we were cracking jokes — but were low-key terrified."

"We were in there for a good hour. It was crazy because it’s the elevator in my building and I walk into that elevator every day and I’ve never seen it the way I saw it that night," explained Cabello. "The mirrors were steamed up like it was a shower because it was so hot and there was no AC."

The two pop stars were soon advised to ease up on the jokes. "Nas’ security guard is like, 'I would keep the chatter to a minimum because you guys are about to start taking up all the carbon monoxide and that’s how people pass out,'" she added. "Nas was like, 'If we weren’t f---ing panicking before, we sure are panicking now.'"

"It was just so crazy. It brought us closer together though," said the "Havana" singer. "Nothing like a trauma bond during a single release."

Once they finally got out of the elevator, Cabello and Lil Nas X headed to Heart — determined to have a good time.

"We were an hour late to the club and we got there and we were like, 'We’re getting black-out drunk. This is a celebration of not just our song, but the fact that we did not get carbon-monoxide poisoning today,'" she said.

Cabello and Lil Nas X recently released "He Knows," a high-energy pop collaboration set to appear on her upcoming album, C,XOXO, set for a June 28 release.

"He’s the kind of artist where it’s more than just the song," she told Rolling Stone of working with the Grammy winner. "He really puts thought and care into the performance. He plays with the fans. He cares about the music video and making a statement."
