The “Teen Mom 2” cast is back for another season of mom drama. MTV has confirmed that Season 7 of the hit docuseries will premiere Monday, March 21.

MTV’s promo video for the new season doesn’t reveal if all of the original moms – Jenelle Evans, Kailyn Lowry, Leah Messer and Chelsea Houska – will return. Despite rumors she may not continue starring on the program, the Ashley’s Reality Roundup reports that Leah has been filming for the show and will reprise her role.

In the past several months, Leah has been engaging in a custody battle with her ex-husband Corey Simms over their twin girls, Ali and Aleeah. According to the Ashley, their custody drama will “definitely be shown” in Season 7 as “MTV cameras were present outside the courtroom for the cases.” As it was on previous seasons, the actual cases will not be shown on TV.

Leah lost primary custody of the twins in October 2015 after Corey told a judge that his ex was making their kids late for school. Leah called his accusations false and promised to fight back. She regained joint custody of the girls in January, US Weekly reports.

It appears Leah’s co-stars are also in store for a jam-packed season. Kailyn, who is fresh off several major plastic surgeries, will be dealing with her husband Javi Marroquin's deployment. A recent blog post from Jenelle reveals she is is still fighting her mom, Barbara Evans, for custody of her son Jace. Viewers will also likely be introduced to her latest boyfriend, David Eason. Chelsea has a joyous season ahead. She accepted her boyfriend Cole DeBoer's marriage proposal in November.
