Teen Mom 2 star Leah Messer, 19, can begin to breathe easier now that her daughter, Aliannah, 2, is starting to develop like her twin sister, Aleeah. It is such a huge milestone! 

Ali is able to walk when someone stands behind her while holding her hand, a source close to Ali’s father, Corey Simms, 21, tells US Weekly. “It’s a major step toward walking solo,” the source adds.

The under-developed twin is anxious to join her sister while she plays. “She wants to be able to run around and play with Aleeah!”

Best of luck, Ali! That’s so great!

Teen Mom 2 stars Leah Messer and her ex-husband Corey Simms entered their 2-year-old twin daughters Aliannah and Aleeah into a Feb. 11 baby beauty pageant in Charleston, W.V., and HollywoodLife.com was on the scene for the big debut!

Leah and Aliannah were the second contestants to the stage. Leah had her adorable daughter blow kisses to the crowd when they first entered. By the time they got to the center of the stage, she put Aliannah down in front of her, where she waved her arms around and smiled. Aliannah had on a cute dress — the top part was all white and the bottom had a pink puffy tutu. The announcer talked about Aliannah and how she likes to play with her sister and wear her mother’s shoes. The audience then cheered as the duo left the stage.

Next up was Corey and Aleeah, but Aleeah was having a fit. He held her hand and they walked to the stage together. Leah’s mom was in the audience coaxing her granddaughter to wave, so Aleeah waved at her. She stayed with her dad the whole time. They had stickers with their numbers on it and she ripped it apart and the audience broke out in laughter. At that point, Aleeah went to the front of the stage, but Corey held her back so she wouldn’t fall off. The announcer said Aleeah likes to play with her sister as well and enjoys Elmo and Barney. She was wearing a similar dress to her sister, but it was all pink.

After they were both done on stage, Corey and Leah took the kids to see their grandparents.

Meanwhile, MTV cameras captured the whole thing — we’re not surprised, as it was adorable!

Do YOU think Aliannah and Aleeah have a future in modeling, HollywoodLifers?
