The couple almost made their fantasy come true, if it wasn't for a fellow passenger.
Aubrey O'Day's attempt at fulfilling her fantasy of joining the Mile High Club was a disaster.
In a preview for Friday night's episode of "Marriage Boot Camp: Reality Stars," O'Day and her co-stars, including her now ex Pauly D, play a game of "Truth or Dare." During the game, the "Making the Band" star told a story about how she once attempted to have sex with Pauly on a plane.
"I pick truth," O'Day says in the clip, reading the card. "Name a place you've always fantasized having sex and why?"
"Easy," she immediately answers. "So Pauly never goes on a plane unless it's first class, and he actually gave up his first class seat to come sit with me. Igave him some sex on the plane for doing that. We were like trying it every which way."
"We had a blanket over us, there was like this really strange man sitting next to us in coach," O'Day continues and Pauly adds, "He was like sleeping. The dude was weird."
Although O'Day wanted to show her gratitude for the "Jersey Shore" star flying in coach with her, the singer explains that the couple just "couldn't get the dynamics of it right."
"My fantasy is successfully getting it done," she adds.
Pauly tells O'Day in a confessional that they should try to bang on a private jet, but O'Day replies that it wouldn't be as fun, because the whole thing is "you risk the danger of getting caught."
Watch Pauly take his turn in the clip below.
"Marriage Boot Camp: Reality Stars" airs Fridays at 9 p.m. ET on WE tv.
