Jonathan Keith Gosselin was born and raised in Wyomissing, Pennsylvania, as the middle child in a family of three children.

[2] Gosselin's mother, Pamela Castello (née Lyum),[3] was born and raised in Hawaii as a second-generation Korean American.

[8] On May 10, 2004, Kate gave birth to sextuplets: sons Aaden Jonathan, Collin Thomas, and Joel Kevin, and daughters Alexis Faith, Hannah Joy, and Leah Hope.

They received local media coverage until the sextuplets were 17 months old, when Discovery Health offered the couple a reality series chronicling the lives of their family.

Both specials received high Nielsen ratings, and Discovery Health signed the couple to a series that aired beginning in April 2007.

[11] Gosselin then began looking for a new apartment in New York City, reportedly visiting Donald Trump-owned Trump Place in Manhattan's Upper West Side.

[14] Gosselin released a statement in response, noting that his wife was the first to make a legal move, and speaking of his continuing love for his children.

[20] However, on October 1, 2009, People.com reported that Gosselin filed a legal action against TLC to prevent the show from resuming and would consider the entry of production crews into the family home as criminal trespassing.

[23][24] In late September 2009, Gosselin filed paperwork seeking to stall the divorce for 90 days, saying, "I regret my conduct since Kate and I separated ...

[26] On October 15, 2009, it was announced that TLC had filed suit against Gosselin for allegedly violating their contract with paid and unpaid television appearances he had recently made on several media outlets.

Alexis, Aaden, Leah, and Joel moved with Kate to North Carolina when she relocated to the state in March 2021.

[31] On August 22, 2017, the police were called to an orthodontist's office in Wyomissing, Pennsylvania, after Gosselin and Kate got into a custody dispute over one of their sextuplet daughters.

No one was arrested, and in the end, Gosselin took the daughter home while Kate was referred to Berks County District Attorney's office for a more clear interpretation of the child custody agreement.

[35] On December 4, 2018, Gosselin won sole physical and legal custody of Collin, as Kate and her attorney failed to appear.

A note with his ex-girlfriend's name was found attached to Gosselin's dresser with a knife, but law enforcement officials stated that did not prove she was associated with the acts.

[43][44] In December 2024, Gosselin and his fiancé Stephanie Lebo revealed in an Entertainment Tonight interview that they had recently gotten engaged after dating for three years.
