What Does Ryan Edwards Think Of Maci Bookout's Pregnancy News?

On Friday, Us Weekly announced Bookout would be joined by Farrah Abraham on the upcoming fifth season of Teen Mom, which has been rennamed Teen Mom OG (Original Girls).

In an interview with the magazine, Teen Mom creator Lauren Dolgen spoke of the network's decision to bring Abraham back, and revealed her co-stars, Bookout, Catelynn Lowell and Amber Portwood, weren't thrilled with the news.

“We had shot a couple of story lines and there is something about having that fourth story to counterbalance — there’s just a magic to four stories and four different points of view,” she said.

Unfortunately, the other girls don't feel the same way.

“[They] know that she's coming back, and it did create a little bit of controversy that will play out in the series," Dolgen explained.

After Teen Mom season four came to a close, Abraham left the series and claimed she was moving on from the show. Around that time, many of her co-stars expressed their disgust with her sex tape.

Teen Mom season five will air later this year on MTV.
