"Teen Mom OG" stars Catelynn Lowell and Tyler Baltierra have officially unveiled daughter Novalee Reign to the world. The couple have shared many photos since their daughter was born, but none of the little girl's face -- until now.

Baltierra uploaded a photo to his personal Instagram page today to celebrate Novalee being nearly 3 months old. The photo shows the wide-eyed tot staring right into the camera, showcasing her baby blues. She's photographed wearing a tiny pink onesie that reads, "I love Mommy."

"Our little tootie is almost 3 months!," Baltierra wrote. "I seriously can't get enough of her. Being a father is the best thing that has ever happened to me, every time I look at that face I fall in love more and more #NovaleeReign #MyGirl"

Lowell later gifted fans with yet another glimpse at her daughter's face. The 23-year-old shared a photo of the baby sound asleep. 

"Our little sleeping beauty," she wrote.

The couple has been very public about their excitement since having their daughter, frequently sharing loving messages for her, as well as one another, on Twitter. Most recently, Lowell shared a photo of her kissing the baby, adding, "Being your mommy is the best thing in the world ... you make my days brighter." Although Novalee is the couple's second child, this is the first time Lowell and Baltierra have gotten to act as parents. They put their first child, a daughter named Carly, up for adoption in 2009. Their journey was documented by MTV's cameras on both "16 and Pregnant" and "Teen Mom."

Lowell and Baltierra will be back on MTV when "Teen Mom OG" premieres on March 23 at 10 p.m. EDT. The series will revisit Lowell, Amber Portwood and Maci Bookout, who as teen moms were credited with the show's initial success. Though it was previously announced that fellow former co-star Farrah Abraham would not be featured on the show, MTV recently announced her return. Abraham, who made a sex video in 2013, will not appear until later in the season, as she did not receive the call until filming was well underway. Her co-stars reportedly were not happy about the news, though they all appear to have moved past it.

The "Teen Mom" reboot will follow each of the women as they embark on new journeys in adulthood. For Lowell, that means viewers will join her and Baltierra from the early stages of their pregnancy with Novalee into their first real go at parenthood and everything in between.
