Kaitlyn Bristowe and Shawn Booth are happier than ever!

The engaged couple sat down with ET Canada to talk life after The Bachelorette, which lead to a particularly shocking revelation -- they're in the mile high club!

"It was in the dark, everyone was sleeping! We were watching a movie, we were cuddling. It happened," said Kaitlyn, admitting that an airplane is the craziest place she and Shawn have ever had sex.

Oh, wow!

The couple also addressed haters who said that they will fall victim to the "Bachelorette curse," and not stay together.

"We say to them, 'Your relationship might not work either' but we don't focus on that!'" Kaitlyn said. Shawn added, "If you took 10 normal couples not in reality TV, what's the rate of them working out? It's really the same everywhere you go, online dating, finding someone at the bar."

Kaitlyn, and Shawn, who she chose in the season 11 finale of the ABC series, frequently show their affection for one another on Instagram, like this PDA shot from last week:

They certainly do seem in love, and they ought to be. In July it was reported that Shawn got Kaitlyn a $150,000 engagement ring!

"Honestly, it scares me. It scares the crap out of me," she told ET at the time. "I wear inexpensive things, and it's just bizarre to me to have like a down payment on a house on my finger."

"We've talked about it and it seems like it would be fun. I think if we did that we would probably have a little intimate wedding after."

Speaking of rings, will the couples wedding be a televised affair? The couple told ET Canada that they are considering it, although in that case they'd follow it up with something small.

"We've talked about it and it seems like it would be fun," Kaitlyn revealed. "I think if we did that we would probably have a little intimate wedding after."
