This is called putting your money where your heart is.
Bachelorette lovebirds Kaitlyn Bristowe and Shawn Booth were guests Monday on Jimmy Kimmel Live!, shortly after their romance went public in the ABC dating show's finale. And they vowed not to end up like so many other Bachelor and Bachelorette couples – even wagering money that they'll be married, or at least still together, a year from now.
"Twice a year for like 13 years now, we've seen people get together. They come on the show and they seem to be very much in love … And then the next thing we know, we see them on the cover of a magazine with a tear down the center," Kimmel said.
He added: "Quite frankly, my heart can't take it anymore."
So, he had them repeat some comical vows in which they promised to stay together for at least a year – and if they don't, they have to pay him $1,000 (either as a lump sum or, he joked, in monthly installments of $2.77 for 30 years).
Bristowe, 30, and Booth, 29, who grace the cover of this week's PEOPLE, seem as likely to succeed as any. "I didn't think I could be this happy," Bristowe tells PEOPLE exclusively. Adds Booth: "She just makes me feel different, something that I've never felt before. It's what I've been looking for."
