According to a new report, "most of the girls," including Savannah, Aleah, Summer, Jordan, Savon, Maddy and Autumn, filmed followup scenes throughout the last couple of months and will be seen in the Where Are They Now? airing. However, some of the girls chose not to return.

"Arianna decided against filming with the MTV crew for the special," The Ashley's Reality Roundup reported on Tuesday. Apparently, she "did not enjoy her experience on the show, and does not want any more attention from it."

"Karley, the girl with the twin girls, also did not participate in filming," the site continued. "Karley recently revealed on her Ask account that she was asked to film, but 'for personal reasons' she declined."

Although Arianna and Karley didn't film scenes for 16 & Pregnant: Where Are They Now?, the site claimed they would be featured briefly on the show, via Skype, since they are required, per their contract with MTV, to give fans an update on their situations.

The remaining three girls, which include Courtney, Jazmin and Millina, will likely be featured, as well, although it is unclear whether they filmed scenes for the special or would be doing an interview on Skype.

The Ashley claims the 16 & Pregnant season 5 special will air later this month or in early Jan. 2015.
