Married at 22 and a dad at 23, Jon Gosselin is best known for his family's TLC reality series Jon & Kate Plus 8.
Married to wife Kate since 1999, the couple welcomed twins Madelyn and Cara in 2000. Sextuplets Aaden, Hannah, Leah, Alexis, Collin and Joel were born via in vitro fertilization in 2004.
On the TV series that has thrust his brood into the spotlight, Jon is frequently seen being berated by his wife for things as trivial as not using a coupon and his eating/workout habits.
As the fourth season drew to a close in early 2009, rumors of Jon's infidelity hit fever pitch, with Us reporting exclusively on his three-month affair with elementary school teacher Deanna Hummel.
As Jon & Kate Plus 8's fifth season kicked off in spring 2009 -- drawing a record 9.8 million viewers -- the TLC network announced plans for a 40-episode season. The Gosselins earned a reported $75,000 per episode.
On the June 22, 2009 episode, the couple announced they were separating. Less than a month after Kate filed for divorce, Jon was seen holding hands with student Hailey Glassman in St. Tropez, France. Officially divorced in December 2009, Jon is currently dating Ellen Ross.
