"Teen Mom OG" star Maci Bookout is sparking some major pregnancy rumors. The MTV mom, who is already the mother of three adorable children, Bentley, Jayde, and Maverick, may be pregnant again! The Reality TV star recently posted a photo of herself and her two sons, Bentley and Maverick, on Instagram and fans couldn't help but notice that it appears that Maci may have a baby bump in the photograph.

Is Maci expecting baby number four?

Maci Bookout has revealed that she is done being pregnant, but that she and her husband, Taylor McKinney, may consider adoption in the future.

However, could the couple be getting ready to welcome a surprise baby? Maci has welcomed surprise babies in the past. She got pregnant with her oldest son, Bentley, while she was still in high school and was shocked to find out that she was pregnant with her youngest son, Maverick, just a few months after giving birth to daughter Jayde. The latest picture of Maci could be revealing a huge piece of news for the "Teen Mom OG" star.

More kids for Maci and Taylor?

As soon as the photo was posted online, fans immediately began to speculate about the possibility of Maci Bookout being pregnant with her fourth child. Maci is known for her thin frame, and the photo does seem to hint at a bit of a belly bump.

However, the angle of the snapshot could also be to blame for the pregnancy rumors. Maci is a huge fan favorite among "Teen Mom" fans, and another pregnancy wouldn't completely shock viewers, especially since she's married to her baby daddy. However, it would be a huge adjustment for Maci who is already outnumbered when it comes to the parent to child ratio.

Is this a bad time for a baby?

Sadly, this may not be the ideal time for the reality star to have another child. In the last season of "Teen Mom OG," Maci Bookout revealed that she and husband Taylor McKinney were having marital issues. She claimed that after they put their children to bed, they often have huge fights over little things because they keep a lot of anger inside and let things build up.

The couple began going to therapy, which they said has helped their marriage.

Ryan Edwards drug issues weigh on Maci's mind

Meanwhile, as "Teen Mom OG" fans know, Maci Bookout's ex-boyfriend and Bentley's father, Ryan Edwards, is going through a tough time, and it's been weighing on Maci's mind. Ryan is dealing with substance abuse issues. After a shocking scene in which he was filmed driving under the influence, slurring his words, and falling asleep behind the wheel, Edwards announced that he had gone to rehab. While Ryan and his wife Mackenzie say that he's doing well, Maci has reportedly been worried sick that Ryan will relapse and that their son, Bentley, could be in danger in his presence.

New baby on the way?

Maci Bookout has stayed quiet on the pregnancy rumors, and the silence is leading many fans to believe that the "Teen Mom OG" star could possibly be pregnant again. It looks like only time will tell.
