On Sunday, Jon Gosselin tied the knot with his girlfriend, Stephanie Lebo, in a heartfelt ceremony attended by his children, Collin and Hannah. The wedding took place in Lancaster, Pennsylvania, with the couple exchanging deeply personal vows, as captured in a video shared by Entertainment Tonight.

Alongside Jon’s children, Lebo’s daughter, Juliana, was also present to witness the joyous occasion, according to the report. During the ceremony, Jon, 48, expressed his profound emotions, saying, “Before I met you, I never knew what it was like to be able to look at someone and smile for no reason.”

He went on to add, “I feel like the luckiest man in the world, because I get to grow old with my best friend and the love of my life,” highlighting the deep bond they share.

Lebo, who began dating Jon in 2021, was visibly moved as she prepared to read her own vows, marking a significant milestone in their relationship.

Lebo, who’s been dating Jon since 2021, was clearly touched before reading her own vows.

“I believe in us growing old together hand in hand, as our lives unfold,” she told him. “I believed in us then, I believe in us now, and I believe in us always.”

The “Jon & Kate Plus 8” alum, dressed in a gray suit, held back tears as they kissed after being pronounced husband and wife.

Collin, 21, served as one of his father’s groomsmen.

Jon shares sextuplets with his ex-wife, Kate Gosselin, which aside from Collin and Hannah, includes Alexis, Aaeden, Leah and Joel. The exes also share twins Mady and Cara, 25.

Jon and Kate, 50, divorced in 2009 after 10 years of marriage. She’s now dating her former bodyguard, Steve Neild, whom she recently went Instagram official with.

Both Jon and Collin blasted the news of Kate’s relationship with Neild after Page Six broke the news in September.

“Guess who really ruined the marriage,” Jon wrote via Instagram, sharing a screenshot of Page Six’s coverage of Kate and Neild. “Read for yourself.”

Collin — who’s been estranged from his mother for years — also accused her and Neild of having an affair, which she previously denied.

“What really upsets me is that my mom had an affair with our bodyguard way back in 2009, and for years would share hotel rooms with him while we went on family vacations, while I was in a connected room!” Collin claimed in an Instagram Story.

In happier news, Hannah reunited with her rarely seen sister Mady earlier this month in New York City. The two danced to Lorde’s 2013 track, “A World Alone,” in a TikTok video.
