However, according to a sneak peek of the ABC reality show, all of that stands to change on tonight's installment, which airs at 8 p.m. ET.
When the racecar driver asks Bekah M. is, she demurs.
"I haven't wanted to say," she said. "I haven't been wanting you to see me through the lens of my age."
And while some women in the house feel that Bekah M.'s youth will be an issue, Luyendyk Jr., 36, previously told ABC News that age was not an issue for him.
"It's more maturity and being ready for marriage," he said. "Some people are just at that point in their lives earlier than other people."
