Teen Mom Alum Kailyn Lowry's Son Isaac Is All Grown Up in Heartwarming Prom Photos

The kids from Teen Mom are reaching their own teenage milestones.

And that includes Kailyn Lowry’s 15-year-old son Isaac, whom she shares with ex Jo Rivera, as he recently celebrated a major rite of passage by attending his high school prom.

In a post shared on Instagram May 6, the reality star documented her firstborn’s big night with a series of photos of him sporting a sharp navy blue suit with black lapels and a matching black dress shirt. The photo carousel also included a heartwarming mother-son snap along with pics of Isaac and his brother Lincoln, 11, whom Kailyn shares with ex-husband Javi Marroquin.

And Kailyn couldn’t help but get emotional about the occasion. Alongside a teary-eyed emoji, she captioned the post writing, “Sent @isaacelliottr off to prom this weekend.”

In addition to the sweet photos, the 33-year-old—who is also mom to kids Lux, 7, and Creed, 4, with ex Chris Lopez as well as Rio, 2, and 18-month old twins Verse and Valley with fiancé Elijah Scott—included a screenshot of a cheeky text seemingly sent by Isaac as he prepared for the outing.
