Leah Messer's Daughter, Aliannah, Walks on Her Own — And It’s the Cutest Thing You’ll See All Day! (VIDEO)

We’ve been watching Teen Mom 2 star Leah Messer Calvert’s adorable twin daughters, Aliannah and Aleeah, accomplish many milestones throughout the years, and one of Ali’s biggest ones was caught on camera this weekend!

The adorable glasses-wearing toddler walked on her own, practically leaping across the room from her mom’s arms to embrace her sister, Aleeah. Hands down, this is the cutest thing you’ll see all day.

Leah tweeted this video on Dec. 9, writing: “Aliannah walking to sissy! They're soo adorable!! #BESTFRIENDS.” Aww! Even though Ali takes a tumble, her “sissy” is there to hug — and adorably spank — her after she falls.
