While some of the older Brown children on Sister Wives have explicitly stated that they had no interest in having polygamous marriages of their own in the future, one of the family's daughters may be admitting she's open to the idea after all.

Is Kody Considering A Fifth Wife?

Mykelti Brown, the second-eldest daughter of Kody and Christine, will be graduating high school in the newest season of episodes premiering January 4-and with that entrance into adulthood comes an even bigger question about her future-whether or not she would consider also having a polygamous marriage.

In a sneak peek clip from the new season, the entire family is congratulating Mykelti after her graduation, when her ex-boyfriend John shows up and also begins taking photos with her-which brought their past relationship into discussion once again.

"So when Mykelti and John were dating, that was not something that really would normally happen within our culture," Kody explains in the clip. "it just wouldn't have been acceptable, because you really just date for the purpose of getting married. I'm just glad that they broke up, it just wasn't working."

Mykelti then chimes in, explaining that she definitely wants to get married one day, but will leave the decision about whether it will be a plural one or not up to whether or not she falls in love with a man who prefers a polygamous or monogamous marriage.

"I'm planning to fall in love and then get married, and with my husband, we can decide together if we chose to practice plural marriage, or to live in monogamy," she says. "If I fall in love with a man who already has one wife, then I can discuss that with him and his wife. No matter what, I will either live fundamentalist Mormonism or I will be Mormon. But I don't know on polygamy yet."

Sister Wives returns on Jan. 4 at 9 p.m. on TLC.
