Kailyn Lowry has a model in the family!

The 23-year-old went to NYC this week with her husband Javi Marroquin and her kids Isaac, 5, and Lincoln, 21 months, for New York Fashion Week – and they had a very important reason for being there. The Teen Mom 2 star's oldest son booked a modeling gig and walked down the runway for Bound By The Crown Couture.

The mom-of-two couldn't have been more excited for her son and posted a video of him werking the runway with the caption, "Go Isaac!!"

Kailyn also snapped a photo with her little model after the show, captioning it, "Isaac's first fashion show yesterday!"

How cute! The family made the most of their trip to the Big Apple and Isaac even hailed his own cab.

It's nice to see Kailyn and Javi so happy together with their kids – especially considering the relationship troubles they encountered on this season's Teen Mom 2. We can only imagine how proud they are of Isaac!
