When is the Teen Mom OG reunion? The dramatic season finale left fans practically begging for more, and they won’t have to wait long because the cast will rehash everything that went on this season in a two-part reunion special starting on Monday, April 16 — but not all of the cast members will make an appearance.

Maci Bookout showed up for the reunion, though it is unclear if her husband Taylor McKinney, her baby daddy Ryan Edwards or Ryan’s pregnant wife Mackenzie Standifer were there. Catelynn Lowell and her husband Tyler Baltierra also made it, even though it was unclear at first if they would show up. Cate had just gotten out of a rehab program and it might have been too soon for her to jump back into filming — especially since host Dr. Drew would be asking tough questions about the couple’s heartbreaking miscarriage. But her recovery team ended up giving her the okay to attend.

Amber Portwood — who is currently pregnant with baby No. 2 — and her boyfriend/baby daddy Andrew Glennon did not make it because she was experiencing “vomiting related to her pregnancy,” a source reavealed to Us Weekly. Even though she wasn’t there in person, she did participate by filming a segment via satellite.

And it was unclear if Farrah Abraham would show up to film after she was unceremoniously fired from the show halfway through the season. But sources revealed that Farrah did not in fact attend, and her mother Debra Danielsen showed up on her daughter’s behalf.

Farrah was a polarizing character on Teen Mom OG and while fans seem to have mixed reactions on her departure, her co-star Amber doesn’t seem to miss her at all. “We’re doing good without Farrah,” Amber told In Touch exclusively. “We still have our fans and some of them are really happy about it, so I can’t knock that.” Watch the video below to see Farrah’s statement about her firing.
