Kailyn Lowry's firstborn Isaac has many hobbies (soccer star, budding baseball player and lover of playing sharks), but the "Teen Mom 2" cast member may have to add another extra-curricular to his schedule: modeling. Watch out, Zoolander and Hansel, because you have some competition on the catwalk.

The sweet kindergartner made his runway debut at the Bound by the Crown New York Fashion Week show -- and naturally, his proud mama captured her lovable little boy strutting a stylish look at the fall event.

"Go Isaac!!" the two-time author captioned the Instagram clip above, which features the grinning five-year-old walking the runway in a crisp white dress shirt, black pants and some shades. Oh, and he gave a wave for his proud parent as well.

In addition, Kail shared an Instagram snapshot with the little man of the hour and her husband Javi.

"Isaac's first fashion show yesterday! #nyc #NYFW" she added. And we have a strong feeling it won't be his last time being front and center in this type of arena.

Share your congrats for I in the comments, and be sure to catch him -- and the rest of his family -- on "Teen Mom 2" every Thursday at 10/9c!
