For some celebrities, aviation is an aphrodisiac that's propelled them into the Mile High Club.
Chrissy Teigen said she and husband John Legend joined the mile-high club in first class.
According to a Cosmopolitan interview published in April 2014, Teigen said she and Legend were flying to Thailand to visit her parents when they felt, um, inspired.
"We were under a blanket," added Teigen. "We weren't even in one of those pod things."
Teigen touted their discretion: "I feel like we should get a trophy for that."
Janet Jackson seemed more embarrassed by her membership when she mentioned it in 2006.
As a guest on Tyra Banks' talk show, Jackson needed to be coaxed by the host to reveal the craziest place she'd ever had sex. At first, she limited her description to a "public place," then confessed she'd experienced it in an airplane cabin. Members of the audience gasped.
Yes, in the cabin, rather than the bathroom. "See, that's what makes it worse," Jackson added.
Chris Brown claims to have done his work undercover.
Responding to what's become a popular TV-interview question, Brown confessed on BET's "106 & Park" in April 2013 that the craziest place he'd had sex was on an airplane. The singer said his first-class seats were big enough "so you can put the cover up, so don't nobody see nothin'."
Miranda Kerr's mile-high moment may have been a bit more nuanced.
Although it's unclear if the supermodel's in-flight sexual experience involved intercourse, she did tell British GQ, "Let's put it this way, I've had an orgasm in the air before. Alone. And together."
Kris Jenner and then-husband Bruce Jenner weren't subtle about their mile-high tryst.
It happened before Bruce, now known as Caitlin, publicly identified as transgender.
According to Kris, the couple tried to conceal their sex in the airplane's bathroom.
"We came out and nobody said anything," Kris told Cosmopolitan in 2015. "And at the end of the flight, the flight attendants got on the microphone, and congratulated us with a bottle of Champagne, and told the entire flight." Kris said getting busted for it was her "most embarrassing moment."
As a guest on Ellen DeGeneres' talk show in 2015, Johnny Depp fessed up to in-flight antics.
While playing the party game "Never Have I Ever" with "Mortdecai" co-stars, Depp was asked if he'd ever joined the mile-high club. He laughed and held up a paddle marked with the words, "I have," but didn't elaborate. And because the game immediately moved on, that's all the info he offered about it.
