Though Chelsea Houska and baby daddy Adam Lind are actually never ever getting back together, there was a time when Chels was torn about letting her main squeeze go.

In the heart wrenching promo for Season 4 of Teen Mom 2, Chelsea admits to a protection-free hookup with Aubree’s father.  “I hooked up with Adam the other night,” Chelsea revealed to her mother. “I’m not on birth control.”

In the Season 4 premiere, Chelsea elaborated on what happened. According to Chels, her IUD somehow mysteriously fell out — but that stop her from jumping Adam's bones when he dropped by for a visit. Instead of using a condom, they decided on the risky "pull out method," which doesn't give Chelsea much peace of mind in hindsight.

We all know what happened the last time these two went sans-contraceptives! Fortunately, Chelsea fans know that this Teen Mom 2 star only has one little lady and plans on keeping it that way for a while.

Are you surprised that Chelsea would hook up with Adam without protection again? Tell us your thoughts below!
