Former "Bachelorette" Kaitlyn Bristowe and her fiance Shawn Booth have defied the odds... at least according to Jimmy Kimmel.

And now the funnyman may owe them $1,000.

How did this happen? Let us explain...

On July 27, 2015, the Canadian-born beauty picked Shawn as her man during the finale of the 11th season of "The Bachelorette." They got engaged on the finale, too.

A few hours after the episode aired, the happy couple appeared on "Jimmy Kimmel Live." Jimmy, like the rest of us, has seen many reality TV couples' relationships falter all too quickly, so he made a bet with them, making them swear on a stack of Us Weekly magazines that they would either be married or still together by July 27, 2016. If they weren't, they owed him $1,000.

Well, they're still together.

On July 27, Kaitlyn took to Twitter to show a clip from the previous year.

"We swore on a stack of @usweekly mags & kept our promise @jimmykimmel," she said. "@JimmyKimmelLive does this mean jimmy owes US?"

Kimmel's response: "I'd need to see you to make love for verification."

Shawn also posted the year-old video to his social media pages. But, he seems to be looking for a bigger payday than a measly $1K

On Instagram he asked, "Double or nothing @jimmykimmel?"

Double or nothing @jimmykimmel?

During Jimmy's hilarious pledge, he made them say the words, 'We, Kaitlyn and Shawn B., do solemnly swear that we are in love, that we will get married or we will at least be together one year from today.

"Because if we're not, this was a huge waste of everybody's time, including ourselves. If we are not still in a committed relationship on July 27, 2016, we will pay Jimmy Kimmel $1,000."

To be fair, the couple does seem committed.

"We're living together, we're enjoying being engaged. When we start to plan [the wedding], we'll let everybody know!" Kaitlyn told People magazine in February.

Shawn added, "The pressure [to wed] doesn't get to us at all...We're both normal people and the most normal thing we can do is wait."
