“Teen Mom 3” Mackenzie Douthit is currently pregnant with her second baby (it’s a girl this time!) As I reported earlier poor Mackenzie broke her foot recently, hence the crutches in the photos. The MTV star was kind enough to share this photo on her instagram with the caption: “18th week. For everyone asking how big I am…. not going to post these often but here ya go. Yes i sleep in joshes shorts”
