Maci Bookout might just be pregnant with her fourth child but if she isn't, she isn't revealing her baby news quite yet. As she and her co-stars film the upcoming eighth season of "Teen Mom OG" with new cast member Bristol Palin, Bookout continues to face pregnancy rumors after her fellow MTV reality star, "Teen Mom 2" cast member Kailyn Lowry, shared a suspicious photo on her Instagram page.

Several days ago, after taping an episode of her podcast series, "Coffee Convos" with co-host Lindsey Chrisley, Lowry posted an image of herself and Bookout and in the photo, Bookout seemed to be sporting a baby bump.

Although she was facing the camera, fans flooded Lowry's page with questions and congratulatory messages regarding Bookout's potential pregnancy. Now, days later, a source is revealing new details about Bookout's possible baby news.

Maci Bookout might be sporting a pregnancy glow

“[Maci Bookout] hasn’t gone public with a pregnancy confirmation yet, but she’s absolutely glowing,” an insider close to Bookout and McKinney revealed to Hollywood Life on August 6. "Nobody has seen [Maci and Taylor] this happy in ages," the source added. According to the insider, those close to Bookout are keeping their fingers crossed and hoping that the longtime reality star will soon make an announcement about a pregnancy.

However, because of Bookout's 2017 miscarriage, it's understandable that she would want to keep any potential news to herself until she's far along in her pregnancy.

“When [Maci] suffered a miscarriage after [her son Maverick Reed], she really wasn’t sure that she ever wanted to risk trying for another child again," the insider continued.

As fans of "Teen Mom OG" will recall, Bookout opened up about her miscarriage during an episode of the show months ago and admitted that the situation was traumatic for her. That said, she and husband Taylor later decided that if they get pregnant again, they will happily expand their family.

Maci Bookout is open to adoption

In addition to being open to conceiving her fourth child with husband Taylor McKinney, Bookout has also considered adoption and spoke of the possibility on "Teen Mom OG." At one point, Bookout didn't seem to be open to anything but adoption but after talking things over with her husband, she decided that she wasn't against the idea of another pregnancy.

"Teen Mom OG" season eight is expected to air sometime this fall.
