The Three Daughters: Names, Ages, and Latest Milestones in 2025

Leah Messer’s life revolves around her three girls, each with a distinct personality and their own unique challenges and triumphs.

1. Aliannah "Ali" Hope Simms

Ali, one of the fraternal twins, is 15 years old as of December 2025. She is the daughter of Leah Messer and her first ex-husband, Corey Simms. Ali is known to fans for her sweet nature and incredible resilience in the face of her health challenges.

  • Current Age (2025): 15 years old.
  • Father: Corey Simms.
  • Latest Milestone: Ali recently started high school, a major transition that Leah and the family celebrated.
  • Health Update: Ali was diagnosed with Titin Myopathy, a rare and progressive form of muscular dystrophy (MD). In a promising update, Leah shared that a recent doctor’s visit brought "promising news," noting that the type of MD Ali has is no longer considered as rare as it was at the time of her initial diagnosis. This positive outlook is a testament to Ali’s strength and the family’s dedication to her care.

2. Aleeah "Gracie" Grace Simms

Aleeah, the other twin, is also 15 years old and shares the same father, Corey Simms. Gracie is often portrayed on the show as the more outspoken, energetic, and spirited of the two.

  • Current Age (2025): 15 years old.
  • Father: Corey Simms.
  • Latest Milestone: Like her twin, Gracie has entered high school, marking a significant step into her teenage years.
  • Personality: Fans often see Gracie as a natural leader and a fierce protector of her sister, Ali, showcasing a strong bond between the twins.

3. Adalynn "Addie" Faith Calvert

Adalynn, affectionately called Addie, is 11 years old and is the daughter of Leah Messer and her second ex-husband, Jeremy Calvert. Addie has become a fan favorite for her hilarious, sassy, and unfiltered personality, which often provides much-needed comic relief on the show.

  • Current Age (2025): 11 years old.
  • Father: Jeremy Calvert.
  • Latest Milestone: Addie is navigating her pre-teen years and continues to be a vibrant, energetic presence in her family’s life, often challenging her mother's "strict parenting" style in humorous ways, as seen on *Teen Mom: The Next Chapter*.

The Co-Parenting Success Story with Corey Simms and Jeremy Calvert

One of the most compelling and current storylines in Leah’s life is the successful co-parenting relationship she has established with both of her ex-husbands, Corey Simms and Jeremy Calvert. This dynamic, which was once fraught with tension and legal battles over custody, has evolved into a stable and respectful partnership for the sake of the children.

From Conflict to Cordial: A Unified Front

Leah has repeatedly acknowledged that getting to a "good place" with both Corey and Jeremy was "absolutely" hard work. However, the trio now maintains a cordial and supportive relationship, frequently coordinating schedules and attending their daughters' events together. This unified front provides a stable foundation for Ali, Aleeah, and Addie, a stark contrast to the drama seen in earlier seasons of *Teen Mom 2*.

The shared focus on Ali’s muscular dystrophy diagnosis was a major catalyst in bringing Leah and Corey Simms closer as co-parents. They learned to put aside their personal differences to ensure Ali received the best possible care, a theme that has continued to define their relationship.

Similarly, Leah and Jeremy Calvert have successfully navigated their post-divorce relationship, maintaining a close friendship and a commitment to raising Addie together. This positive co-parenting environment is a key reason why all three girls appear to be thriving in their teenage and pre-teen years.

Ali’s Health Journey and the Power of Hope, Grace & Faith

Ali’s battle with Titin Myopathy remains a central, yet increasingly hopeful, part of the family’s narrative. The condition affects her mobility and requires ongoing medical attention, including the use of a wheelchair for longer distances.

Promising Medical Updates

The latest medical updates shared by Leah Messer in 2025 are overwhelmingly positive. Doctors have noted that the treatment landscape for Titin Myopathy is improving, and the family is encouraged by the progress and strength Ali continues to show. Ali’s determination, whether she is navigating the halls of high school or dealing with doctor's appointments, has been a major source of inspiration for her mother and fans worldwide.

Leah's Personal Growth and Autobiography

Leah’s journey as a mother, including overcoming a past struggle with prescription pill addiction and dealing with the stress of Ali’s diagnosis, is chronicled in her autobiography, *Hope, Grace & Faith*. The book details how she had to "hit rock bottom" to realize the importance of self-love and self-improvement to be the best mother for her girls. The title itself is a nod to her daughters’ middle names and the core values that have guided her parenting style.

By prioritizing her mental health and sobriety, Leah has built a solid "foundation" for her daughters, focusing on raising "strong women" who are equipped to handle life's challenges. This focus on personal development and positive parenting is the ultimate update in the Leah Messer family story.
