, pointing out that in several shots, while the castmates all share a toast of various spirits, Maci is drinking what appears to just be water.
In another shot, Maci has what appears to be hiding what looks like a growing baby bump.
The excited fan/sleuth captioned her find: "YA’LLLLLL - No one is talking about this yet. Proof Maci is totally pregnant for this reunion."
The upcoming series already looks to be an emotional journey for Maci, who in another sneak peek sobbed as she confessed that she felt she's 'not enough' and is 'chasing' acceptance.
The clip, which was shared on the Teen Mom Instagram page, kicked off with the emotional moment, which appeared to show the stars - including Maci - participating in a sharing circle-type game.
Maci is called to step forward, but plays coy saying: "I'm not sure I'm ready."
Her co-stars encourage her and she steps into the middle of the circle.
Once there, Maci shouts: "I am not enough."
At that point, she's asked: "What does 'enough' mean for you," to which she replied: "I don't know and I've been chasing it my whole life."
Maci is then asked: "Chasing what?" to which she says, "Acceptance?"
She was then asked when she realized she's "not enough," to which she said: "When I realized that I found confidence in taking care of everyone else.
"Make sure everyone else is OK, and when you're s**t gets real, go away. Run. Run."
Amber Portwood then appears, speaking in a confessional interview.
She says: "I heard her say something that has been known for a very long time with a lot of the older OGs: she does not put herself first."
The clip then returns to the vulnerable moment, where Maci is asked, "at what point are you gonna start to put yourself first?"
She replies: "Now. Right now" and gives a high five.
EMOTIONAL DIFFICULTIES
Even before the reunion series, Maci was having emotional difficulties.
During the shows initial reunion special, with Dr. Drew, the Teen Mom fought back tears as she opened up about feeling "disconnected" from her "emotions" and marital struggles.
Ahead of Part 2 of the reunion special, the Teen Mom Instagram page shared a clip from Maci's sit-down with Dr. Drew.
The interview began with the 30-year-old discussing her relationship with her eldest son Bentley.
"If I'm being honest it hasn't really improved," Maci confessed about her bond with the 13-year-old.
She went on to explain that she realized she was acting "selfish" and has an "unhealthy relationship with emotion."
The TV star began to fight back tears as she got vulnerable about her feelings of "homesickness" and fears of being alone.
"I wasn't home by myself so when I was alone, I wasn't comfortable, and I needed that to change. But because I disconnected all emotions, I didn't know who I was. So it was scary, so I didn't feel safe alone," she continued.
Maci got emotional saying: "I'm trying not to shut down," as Dr. Drew handed her a tissue.
MISCARRIAGE
He then asked the mom-of-three what triggered the feelings of "homesickness," to which she revealed they began after her miscarriage.
In 2017, during an episode of Teen Mom OG, Maci revealed they had miscarried their third child together - a girl they had called Dandelion.
"I just love the human I am now. I'm not a robot," Maci declared through tears.
The MTV star explained how she feels now since coming to terms with her emotions revealing: "I'm present instead of possessive. I'm here, I'm present and it's beautiful and it's fine."
MARITAL STRUGGLES
The conversation then shifted towards Maci's marital issues as her husband Taylor, 32, joined her on stage.
"We lived a good life, I'm just glad I got him. He's wonderful," Maci said before turning towards her husband adding, "You're wonderful."
"Sometimes we fight over the most ridiculous stuff," Taylor joked
Dr. Drew asked the couple about their reasoning behind attending therapy together, to which both agreed to be lack of "communication" and "prioritizing" one another.
Maci then revealed how vital intimacy is to her in a relationship, adding "it's my love language."
"I don't need you to tell me I'm pretty and say 'thank you.' Like, just grab my a** and give me a kiss on the cheek, we're good," she explained.
