Aleeah Grace Simms, better known by her nickname Gracie, is the daughter of MTV reality stars Leah Messer and Corey Simms. She’s been in the public eye since birth, thanks to her family’s appearance on Teen Mom 2, one of the longest-running reality franchises on television.
Born on December 16, 2009, in West Virginia, Aleeah arrived alongside her twin sister Aliannah. Their birth was documented during the early days of the Teen Mom franchise, and millions of viewers have watched the Simms family grow over the years. Now 16 years old, Aleeah remains best known as part of the Messer-Simms family that became a household name through MTV.
Early Life and Family
Aleeah Grace Simms was born and raised in West Virginia. Her early years played out on national television as Teen Mom 2 followed her parents’ journey through young parenthood. The show gave audiences a window into the Simms family’s daily life in West Virginia, from early milestones to the ordinary rhythms of raising young children.
The Simms family is a blended one, and that dynamic has been a recurring theme across the many seasons of the show. Aleeah grew up alongside her twin sister Ali and later her younger half-sister Addie, and the bond between the three sisters has been visible throughout the series.
Who Are Aleeah Grace Simms’ Parents?
Aleeah’s mother is Leah Messer, who first appeared on MTV’s 16 and Pregnant before becoming a main cast member on Teen Mom 2. Born on April 24, 1992, in Elkview, West Virginia, Leah went on to become one of the most recognizable faces in the franchise. She’s appeared across multiple seasons and spinoffs, including Teen Mom: The Next Chapter.
Her father is Corey Simms, who also appeared on Teen Mom 2 during the earlier seasons. Corey hails from West Virginia and was part of the show primarily during the co-parenting storyline with Leah. He’s kept a more private profile compared to other cast members over the years.
Leah and Corey’s relationship — and their experience navigating parenthood at a young age — formed one of the core storylines when Teen Mom 2 premiered in January 2011. The couple later separated and have co-parented their twin daughters since.
Leah went on to marry Jeremy Calvert, with whom she had a daughter, Adalynn, before that marriage also ended. Corey also moved forward with his own family life. Despite the changes, the co-parenting arrangement between Leah and Corey has remained a visible part of the show’s narrative.
Who Is Aleeah’s Twin Sister?
Aleeah’s twin sister is Aliannah Hope Simms, known as Ali. Born on the same day — December 16, 2009 — Ali has been diagnosed with a form of muscular dystrophy called Titin myopathy, a rare genetic condition that causes progressive muscle weakness.
Ali’s health journey has been one of the most talked-about storylines across the entire Teen Mom franchise. Their mother Leah has openly shared updates about Ali’s diagnosis, treatment, and progress throughout the show’s run. Despite the challenges that come with the condition, Ali has shown resilience and determination in pursuing her own interests.
Aleeah also has a younger half-sister, Adalynn Faith Calvert, known as Addie. Born in February 2013, Addie is the daughter of Leah Messer and Jeremy Calvert. All three sisters have appeared together on Teen Mom 2 and its successor series.
Growing Up on Teen Mom 2
Teen Mom 2 debuted on MTV in January 2011, and Aleeah was part of the show from the very first episode. She was just over a year old when the series began airing. Over eleven seasons, viewers watched her grow from an infant into a teenager.
The show documented the everyday moments of family life — holidays, school milestones, and the kind of ordinary interactions that made the Teen Mom franchise relatable to its audience. Aleeah and her sisters were frequently at the center of those scenes, offering a look at what childhood and adolescence looked like inside the Messer-Simms household.
When Teen Mom 2 ended, the franchise continued with Teen Mom: The Next Chapter, which kept following several of the original cast members, including Leah. The show’s long run means Aleeah has spent the majority of her life with cameras as part of her family’s routine.
Outside of the show, Aleeah has been known to participate in cheerleading, based on appearances and moments shared during the series. Like many teenagers her age, she’s navigating adolescence — just with the added layer of having grown up on one of MTV’s most-watched reality shows.
