Sure beats diaper duty! Teen Mom OG stars Farrah Abraham, Catelynn Lowell, and Amber Portwood took a night off from their parenting duties to attend the 2015 MTV Movie Awards on Sunday, April 12. 

Though fans are used to seeing these three stars in their comfy casual attire on the MTV reality series, they went all-out for their red carpet appearance. 

Erotic novelist Abraham, 23, showed off a slim frame in a cleavage-baring, cutout silver gown, while Portwood, 24, opted for a short, long-sleeve white dress with a blue belt. Lowell, 23, who welcomed daughter Novalee Reign on New Year's Day, wore a floor-length navy gown with a white jacket over top. 

Each reality star brought her own escort. Lowell attended the event with her longtime love and fiance Tyler Baltierra, while Portwood proudly walked the carpet with her new fiance Matt Baier

Abraham brought her new boyfriend Simon Saran, who sported a shiny gray suit to match his date. Noticeably absent was their pregnant costar Maci Bookout, but considering she's getting closer and closer to her due date for her second child, it's not surprising she stayed home. 

"the #TeenMomOG ladies looked beautiful last night at the #MTVMovieAwards @CatelynnLowell @AmberLPortwood @F1abraham," she tweeted in support of her fellow stars.
