On her official Facebook page, the Teen Mom 2 star, 22, proudly posted pics of her girls participating in a dance showcase at Famous Superstars in their native Charleston, West Virginia.
Both Aleeah, also known as Gracie, and her sister, who suffers from a rare form of muscular dystrophy, were dressed in spandex short shorts and tight bikini tops. They even wore bright red lipstick.
While many called the girls "beautiful" and "pretty," some fans expressed their concern over the mature attire. "Why are they dressed so scantily?" asked one woman.
Psychologist Dr. Judy Kuriansky tells RadarOnline.com that the tiny reality stars look "inappropriate" for their young age.
"They are being pushed to dress sexy," says the author of 31 Things to Raise a Child's Self-Esteem. "The fit and level of exposure is inappropriate for pre-adolescent girls. It seems the dance teachers are trying to garner attention."
In addition, she believes Aleeah is posing provocatively. "She's sticking her stomach out and tilting her head, while Ali looks like a shy little girl," she observes. "There will likely be sibling rivalry down the line."
