Farrah Abraham and her Teen Mom OG costars Amber Portwood and Catelynn Lowell walked the red carpet on Sunday at the MTV Movie Awards. This must have been a thrill for fans of the show who are used to seeing the Teen Mom clan decked out in casual ‘mom’ clothes. Amber Portwood, Catelynn Lowell, and Farrah Abraham got all dolled up in classy attire for the MTV event.

According to a report from Us Weekly, Farrah Abraham–known for her time as a porn star and an erotic novelist, in addition to being a Teen Mom–wore a cutout silver gown that showed off her ample (surgically enhanced) cleavage.

Amber Portwood looked very pretty in a short white dress with long sleeves, that she cinched with a cobalt blue belt. Catelynn Lowell wore a floor-length navy blue gown that she topped with a white jacket.

Simon Saran accompanied accompanied Farrah Abraham to the MTV Movie Awards. Catelynn Lowell attended the event with longtime boyfriend and now fiance Tyler Baltierra. Amber Portwood only recent became engaged, and she brought her new fiance, Matt Baier, to the event. The girls did pose as a trio, however, for the cameras during their time on the red carpet.

Fans of Teen Mom OG no doubt noticed that one of the show’s stars was noticeably absent from Sunday’s walk on the red carpet. Maci Bookout is getting close enough to her due date with her second child that she felt she’d better stay home.
