Jon and ex-wife Kate Gosselin welcomed the sextuplets in 2004, three and a half years after they had twins Cara and Mady, now 22. The entire family found fame on TLC's Jon and Kate Plus 8, which followed the Gosselins' lives parenting their uniquely large brood.

The pair continue to be estranged, with Jon assuming physical custody of Hannah and Collin several years ago while Joel, Aaden, Alexis and Leah continued to lived with Kate. Cara and Mady headed to college in 2019.
