Are you ready for a 3 minute blast from the past? OK! Magazine dug up a video from December 2011, before the start of Teen Mom 2, Season 2. As OK! notes, this a long time before Jenelle Evans got engaged to Courtland Rogers, Leah Messer was pregnant with her third child, or Kailyn Lowry married Javi Marroquin. In the video, the moms share retroactive advice for themselves, including Jenelle saying, “I would definitely tell myself how hard it is to be a teen mom, and…birth control.” Jenelle promotes safe sex a couple of times during the video, which is especially interesting to watch now, knowing how much has changed for all of these girls in the past year.
