Dax Shepard may have helped Kristen Bell face the 鈥渢oxic鈥 behavior that was threatening their relationship, but that doesn鈥檛 mean that they don鈥檛 have their fair share of fights. They once had two tiffs in a single motorcycle ride, in fact.

Chatting with Jimmy Kimmel on Tuesday, Bell opened up about a road trip the couple took from New York City to Detroit early on in their relationship. The Good Place star wasn鈥檛 keen on her bae鈥檚 choice of 鈥測acht rock outlaw country鈥 music, so when they stopped for a break, she decided to swap it out for some snazzy show-tunes.

鈥淲ell, he was not happy,鈥 the 37-year-old admitted. 鈥淏ecause I didn鈥檛 ask, we didn鈥檛 discuss it, and it was also like, we鈥檙e both control freaks鈥︹ At the time, they hadn鈥檛 yet mastered how to de-escalate their conflicts, so the fight 鈥済ot bigger and bigger鈥 and eventually warped into an argument about an entirely different issue.

鈥淒ax Shepard believes that if he is in a state that does not have a helmet law, he should be 鈥榦bserving the local culture鈥 and not wear his helmet,鈥 Bell explained to Kimmel. 鈥淪o this morphs into an even bigger fight. And we ended up compromising on, if he was on the highway, he had to wear the helmet. But if he was on side streets, he didn鈥檛 have to wear the helmet.鈥

Though it sounds like they found some reasonable middle ground, she added, 鈥淚鈥檓 not joking, he took side streets for like four hours just to make a point.鈥

And it didn鈥檛 end there. When it started to rain, Bell suggested that Shepard wear a helmet regardless of whether he was on a highway. He wasn鈥檛 thrilled. 鈥淭he rest of the road trip, I think through all of Ohio up to Michigan, we were fighting so bad, we both lost our voice because we were screaming at each other on the motorcycle.鈥

You might think it鈥檚 hard to stand your ground on a bike, but Bell told Kimmel, 鈥淚 refused to hold onto him, so I held onto the back of the motorcycle, like a boss.鈥 Like. A. Boss.

When they finally made it to Detroit, Bell鈥檚 mom had set up what she thought was the perfect way to welcome Shepard into their home: She had a stack of ALF videotapes for them to watch. Yes, ALF.

Shepard鈥檚 recollection of that moment, as Bell tells it, is: 鈥溾業 had an out-of-body experience. I hate this girl I鈥檓 sitting next to. We鈥檙e on the verge of a breakup. I think her mom is crazy, and all of a sudden, I鈥檓 watching ALF.鈥 He was fully outside of his body.鈥

The actor only made it through two episodes before excusing himself, but he and the Veronica Mars alum eventually worked things out. (Obviously.)
