On Monday, MTV's "Teen Mom OG" closed the second part of its end-of-season reunion special with a surprising twist: Maci Bookout, Amber Portwood, Catelynn Lowell and Farrah Abraham discussed their relationships with each other.

The biggest surprise came when Bookout sincerely apologized to Abraham, whom she has battled with the entire season.

"I really, honestly never meant to hurt your feelings. It was never my goal, or for you to feel judged by me," Bookout told Abraham.

It is too early to say whether or not the apology quenched the bad blood between the two "Teen Mom OG" stars.

Just days after the reunion, a couple of the moms have enjoyed huge life accomplishments.

Cosmopolitan magazine named Abraham in its list of Internet's Most Fascinating 2015. It's an honor that Abraham feels was well deserved.

"Keep in mind also," Abraham told Cosmopolitan, "that no matter what I've been doing, I've been doing the best in it that we know of. What I'm saying by that is, if I'm developing novelty toys, I'm winning awards. If I'm writing books, I'm a New York Times bestseller -- how do I do it all? I don't know."

She told Cosmo that she is good at multitasking, and thanks God "every day" for her success.

Meanwhile, Lowell and her fiancé, Tyler Baltierra, are finalizing wedding plans. The couple has been together for 10 years, starting their relationship in middle school. This summer they are making their long-time relationship official. The "Teen Mom OG" stars visited Castle Farms, a north Michigan wedding venue, on Wednesday.

Baltierra posted a picture of himself and his bride-to-be outside the venue, along with the caption, "It's so exciting finalizing our wedding plans! Thanks to Johanna & @castlefarms for helping us make this special day perfect, we are so excited! #10weeksToGo #10YearsStrongTogether."
