'Teen Mom 2' Season 5 Trailer Released, Promises Plenty of Drama (VIDEO)

The new trailer for "Teen Mom 2: Season Five" has been released by MTV and promises plenty of the drama fans have come to expect from the teen moms. One burning question is whether Jenelle Evans, one of the four moms featured, had an abortion during filming.

"It would be selfish to Jace if I had another child," Evans says during the trailer. "I decided that I am going to get an abortion."

Many wondered whether that pregnancy ended in a miscarriage, which Evans let everyone know she went through. However, Radar Online has reported that it was a separate pregnancy with husband (soon to be ex-husband) Courtland Rogers.

"She had just started dating Nathan [Griffith]," a source told the website. "It was made to look like it hadn't happened yet, but it already had. Jenelle got the abortion right after she started dating Nate."

Evans is currently pregnant with boyfriend Griffith's child. The two will welcome their first child in 2014, but Evans was recently taken into custody for disturbing the peace during a dispute with Griffith. Their relationship will be explored in-depth on the new season of "Teen Mom 2."

Meanwhile, fans will also be caught up on the lives of Leah Messer, Chelsea Houska, and Kailyn Lowry and their respective families. Messer and ex-husband Corey Simms are still dealing with daughter Aliannah's physical disability, which proves to be incredibly stressful for the both of them.

"No one ever thinks that their daughter will have special needs," Messer says in the promo. "My future with her doesn't look so damn bright."

Houska is dealing with the breakup from her daughter's father, Adam Lind, who ended up having a daughter with his new girlfriend. It's clear from the preview that Houska is having an incredibly hard time coping with all of these changes.

Lowry, who got engaged and married to boyfriend Javi in a civil ceremony, learns that she is pregnant and finally gets the wedding ceremony she dreamed of. Of course, there is plenty of family drama that includes her mother and father of her son, Jo Rivera.

The new season of "Teen Mom 2" premieres on Tuesday, Jan. 21 at 10:00 p.m. ET on MTV.
