Forbidden liaisons! Before The Bachelorette finale aired and the world knew that JoJo Fletcher picked Jordan Rodgers to be her one and only, the couple had to stay apart for months. And though they got to see each other once every two weeks, it proved to be too hard for the pair to remain separate.

"There was one time, we were in L.A. for a couple days -- separate -- so, I borrowed a buddy's Halloween costume, a mullet wig and a trucker hat," Rodgers told ET earlier this month. "And took an Uber to her hotel and was kinda sneaking around a little bit."

"Our producers don't know!" JoJo added. "We didn't get caught! You can't be mad!"

On Monday, Rodgers shared a photo of the infamous meetup on Instagram, writing, “The last time we were in Chico together you might have met our alter egos Goldie and Ricky…oops #sneaky #sorryABC.”

In the hilarious pic, Rodgers is wearing a Cleveland Indians hat with a long, curly black wig and an ‘80s-style zip-up jacket. His future bride is sporting a blonde curly wig with a purple princess hat.
