Tonight's Teen Mom 2 will be an emotional roller coaster!

As seen in a sneak peek for tonight's episode, a very pregnant Kailyn Lowry breaks down during a phone conversation about her third baby daddy, Chris Lopez. "I'm like scared if I call him when I'm in labor or something, he like literally, won't show up," she said. "I'm about to do this by myself."

Chelsea Houska had an emotional moment, but in the best way possible! The mother-of-two tried on her wedding dress and it is absolutely gorgeous.

Briana DeJesus is faced with putting one of her two baby daddies on child support.

Watch the emotional clip above! Teen Mom 2 airs Monday nights at 9pm ET, only on MTV!
