It simply wouldn't be Teen Mom without baby daddy drama, one-year marriages, and cheating scandals. The whole messy chart of who's dating whom can get a little complicated — even for devoted fans.

And now, with Kailyn Lowry admitting she's giving birth to baby No. 3 with a third baby daddy, the tangled web of Teen Mom relationships gets even more chaotic. Fortunately, we created this handy guide to every relationship on Teen Mom, from marriages to alleged drug buddies.

As much as we love seeing the Teen Mom girls get married and move on from their baby daddies, marriages don't seem to last long amongst the reality TV couples. With the exception of Chelsea Houska, who married Cole DeBoer in 2016, and Catelynn Lowell, who married Tyler Baltierra in 2015, all the moms who've been married while on the show are now divorced.

Jenelle Evans married Courtland Rogers back in 2012 in a surprise courthouse ceremony. However, the couple split just a few weeks later, and Jenelle wasted no time moving on to her next relationship with Nathan Griffith, who got engaged twice before they finally split for good in 2015.

“I just want my family together, and I’m sick of starting new relationships," Jenelle said during a Teen Mom reunion. "I want to settle down forever.”

And if you think Jenelle's history is confusing, Leah Messer also has a messy love life. Everything seemed perfect when she married Corey Simms in 2010, but the couple got a divorce when she revealed she cheated on him a week before the wedding! After divorcing, she moved on to Jeremy Calvert, but they divorced two years later, with Jeremy blaming Leah's issues with addiction.

“Too many issues stressing me out,” he said on the show. "She takes prescription pills for her anxiety. I don’t know if that sh—t f—ks with her or what. It’s obvious she has an addiction issue. I’m just done."
