Teen Mom stars Amber Portwood and Gary Shirley's daughter, Leah, reached an exciting milestone. Leah, now 17, looked all grown up while sharing a series of photos from her high school dance via Instagram on Monday, May 4. "Prom 2026!! 🤩 #prom," she captioned her Instagram post. In the pics, Leah wore an embellished red dress with halter neck and a tousled updo with her face-framing pieces down and curled. The 11th grader completed her outfit with black strappy heels, soft makeup with a bright lip and a simple nude manicure with almond-shaped nails.
