When in doubt, just say she's beautiful! Bachelor Ben Higgins and his new fiancée, Lauren Bushnell, put their relationship knowledge to the test in a funny game of Fiancé My Name during their post-Bachelor appearance on Jimmy Kimmel Live!

The lovebirds were star guests on Kimmel's late-night talk show on Monday, March 14, and had no hesitations when it came to playing the game and figuring out exactly how much they did or didn't know about each other.

And it was worth doing their best! There were 10 porcelain dinnerware sets up for grabs if they managed to get the answers right, to help them in setting up their new home together!

The game started off well — both were able to give each other's middle name and the names of their siblings. But when it came to giving their mothers' maiden names things got tricky.

Bushnell went for "Smith," picking a common name in the hope she'd strike lucky. Higgins however decided to use a little charm. "Beautiful," he wrote, hoping to score some points with his future mom-in-law.

Later on in the show, Bushnell revealed that, having lived together, she's discovered her dream Bachelor does have a few annoying habits.

"So Ben is a very heavy breather, out of his mouth," she admitted to Kimmel. "A very heavy mouth breather."

And that's not all! Turns out he's quite loud when he's praying too!

"For example, the other night, I like to pray first before we go to bed," a dejected Higgins continued. "And I'm praying and she stops me, and she says, 'Can you not pray so loud!'"
