Teen Mom OG” star Catelynn Lowell recently shared the exciting news that she and her husband Tyler Baltierra are expecting another baby, which will be the third child for the married couple, as US Weekly Magazine reported on September 23. As teens, the pair decided in 2009 that it was best for their first child to be adopted by a loving family since they were both so young and aimed for their first-born to have all the best life has to offer in a stable and loving home.

The expectant mother also posted the sonogram image of her unborn baby, on Instagram, on September 23. In sharing the sonogram photo, Catelynn captioned her post, noting that she “can’t wait to meet [her] little nugget.” Fans are super thrilled to see not only the image but that she and Tyler are having another baby.

The couple has long been a fan favorite since MTV launched its branded franchise “Teen Mom” reality shows.

While Catelynn's popularity on Instagram flourishes, another former reality television star shut down her Instagram for an unknown reason. Hannah Gosselin's account was suddenly closed after a flurry of media reports about her parents' still feuding over child custody [VIDEO]. Therefore, it is refreshing for fans to follow a reality star, such as Catelynn, whose life is not mired in controversy.

Fans are thrilled to see baby's image

Dedicated fans have followed the couple on MTV from the time when they were making the decision for the future of their first-born daughter, through the ups-and-downs of their teen relationship that grew into a marital commitment in 2015, a miscarriage, and the revelation Catelynn relayed about having mental illness.

Fans feel invested in their lives and thrilled to also share in the couple’s good news.

Catelynn also posted an image, on Instagram on September 20, of the food she is currently craving most during her pregnancy. She captioned the photo: "My number one craving so far!! I could eat the whole jar."

One of her followers, using the online handle @erinhaighs1, responded by stating, "I was in love with hot wings for my son, peaches for my girl." Based on the account user's cravings, she is predicting that Catelynn and Tyler will have a baby boy.

Though the reality show couple was not planning to expand their family anytime soon, it does not diminish the excitement they feel. The young mom, who is now 26, stated that their idea was to wait before having more children in light of her mental health suffering a huge downward spiral following a miscarriage. During an episode of “Teen Mom OG” in February, fans became aware of the loss of Catelynn’s and Tyler’s baby, which happened in January, which E! Online noted.
