Who's pregnant on Teen Mom 2?

When Season 8 picks back up, it will feature four different pregnancies, as Chelsea Houska, Jenelle Evans, Kailyn Lowry, and Briana DeJesus are expecting children — basically the entire cast except for Leah Messer.

Jenelle and David reach their breaking point.

Many of the scenes were filmed in advance, so fans will get to take a look back at Jenelle's pregnancy with her third baby, which marks her first child with her now-fiancé David Eason. The season premiere will feature a super tense moment between the couple, where Jenelle and David get into an argument as tensions arise while they attempt to move out of their old home and get settled into their new one — all while Jenelle is still heavily pregnant.

Chelsea celebrates her baby shower in an untraditional way.

Chelsea is expecting baby No. 2, but it will be her first with her new husband, Cole DeBoer. She decided that she would have a co-ed shower with more of a party vibe, so she went with a "diaper keg party" theme — which included a game where the dad-to-be and a handful of friends chugged beer out of baby bottles to see who would finish first.

Kailyn's relationship with her baby daddy is a touchy subject.

Kail shocked fans when she announced her third pregnancy back in March, since it had only been three months since she finalized her divorce from ex-husband Javi Marroquin. Even though she tried to hide baby daddy No. 3's identity, she would later reveal that Chris Lopez is the father of her unborn child — and on tonight's episode, fans will get a little more insight into why she wanted to keep it a secret.

"He doesn't want to be on the show, he doesn't his name on the show," Kail told her friend via FaceTime. "He probably doesn't want his other hoes to know about me."

Kailyn Isn’t Ready To Talk About New Relationships

Now that things are officially over with Javi, what's the update on Kailyn's love life? ❤️ A new season of Teen Mom 2 starts TONIGHT at 9/8c on MTV!

New cast member Briana makes her debut.

After months of speculation, MTV finally confirmed that they would be adding Bri as the fifth mom on the Teen Mom 2 roster. The former Teen Mom 3 star is currently pregnant with baby No. 2 from baby daddy No. 2, and unlike her co-star Kail, she isn't hiding his identity — and fans will get to see him on tonight's premiere. In a scene from the episode, Bri sat down with Luis to discuss their pregnancy.

"This pregnancy was the last thing that I expected to happen," Bri told Luis. They met at a club and got pregnant less than a month later, but Bri said that she decided to keep the baby because he said he would help her raise their child.
