They were previously one of the blind date teams who were getting along really well on The Amazing Race, but the honeymoon may finally be over for Jeff and Jackie when they run into problems in Bavaria.

Jonathon & Harley Hoping To Appear On Future 'All-Stars' Season?

The couple, who alongside Laura and Tyler and Kurt and Bergen were the only Blind Daters not having major issues in their partnership, appears to come unhinged when they seem to get extremely lost while racing on the 5th leg through Bavaria.

In a sneak peek clip, they seem to truly attack one another verbally after having a huge disagreement over the direction they're taking with their task.

Blind Dates Begin 'Unraveling'

"You're not listening to me," Jackie says in a clip for the Friday, April 3 episode.

"We could be going completely in the wrong decision...we've got to back up to the tower," Jeff says. "I can't do this anymore, This is stressing me out too much."

He then cuts something Jackie says off midway-and that doesn't sit well with her.

"We need to work together, but Jeff just finds a way to shut me down so we can do what he wants at the time," Jackie says in the clip. "But I'm not a lady to be talked down to."

Jackie then makes sure to let Jeff know how upset she is when they later find a car (not theirs, because they find Tyler's fanny pack in it), and prepare to drive off.

"I'll just sit back here and shut up," Jackie says.

"You don't have to do that, you can talk as much as you want, I won't tell you to shut up," he replies.

"Respect me when I'm talking, that's all I ask," she shouts. "Don't cut me off!"

"Jackie, I'm telling you, I'm not going to cut you off again," Jeff replies.

"Just don't cut me off ever again," Jackie continues. "EVER AGAIN! Just don't do it!"

Finally, Jeff has had enough and snaps back at her, blaming them for their current predicament.

"How about you do us both a favor and read the clue! God, you're so f-g annoying!" he says. "You got your point across, shut up please."

The Amazing Race airs Fridays at 8 p.m. on CBS.
