’90 Day Fiance': Nikki Rearranges Mark’s Bookshelf, Ruins His Life (Exclusive Video)

The 39-year age difference isn’t a problem, but grouping science books with music ones is

Do not touch 58-year-old Mark’s books, ladies.

The “90 Day Fiance” star becomes flabbergasted this weekend when his 19-year-old bride-to-be Nikki takes it upon herself to rearrange the bookshelf.

The visitor from the Philippines elected to arrange her future hubby’s books from big to small, whereas Baltimore native Mark previously had them divided by category. Because this is reality TV, this turns out to be a massive problem.

When Nikki hands Mark a stack of his divorce books — which clearly he’s used before — the man of the house states,”Yeah, I’m hoping I don’t have to re-read those.”

Later, after Nikki shoos him away, Mark says: “OK, well I’m curious to see how it all works out.”

We all are, Mark. We all are.

Mark and Nikki met through an online dating site. Mark’s four children from his previous marriage are all older than Nikki, and are concerned that she is young enough to be his granddaughter. Nikki thinks she might want children in the future, but Mark is firm in that he does not want to be a father again.

“90 Day Fiance” airs Sundays at 10 p.m. ET on TLC.
