Leah Messer became an aunt for the second time at the end of last week.

On Instagram, the Teen Mom 2 star revealed that her younger sister, Victoria Messer, had given birth to her first child, a baby girl, and shared a photo of the baby with her many fans and followers.

"Omgoodnesss she is so perfect! #CamiRaeLynn," Messer wrote in the caption of an Instagram photo of herself and the new baby seen below.

Messer later shared a family photo of herself, and her sister and their kids, including her twins Ali and Aleeah, 6, and her daughter, Adalynn, 3.

"My sister was a trooper! Memories that will never be forgotten!! I love them so much! I'm an auntie, again! #CamiRaelynn," Messer wrote with the photo below.

In the years since fans met Messer on Teen Mom 2, the reality star has welcomed three children, two with her first husband, Corey Simms, and a third with her second husband, Jeremy Calvert. Now, however, the reality star is single and reportedly planning to go back to school.

Leah Messer and her family have been filming for the upcoming season of Teen Mom 2 for the past several weeks, but thus far, no premiere date announcement has been made.
