Jon Gosselin is extending an olive branch to his family.
The Jon & Kate Plus 8 star shared that he plans to invite his estranged kids with ex Kate Gosselin—twins Mady and Cara, 23, and Alexis, Aaden, Joel and Leah, four of the former couple's 20-year-old sextuplets—to his upcoming wedding with fiancée Stephanie Lebo.
"I would definitely do that," Jon told Entertainment Tonight in an interview published Dec. 4. "I would definitely send an invite to all of them. You know, they are my kids."
And the 47-year-old—who became the primary guardian of remaining sextuplets Hannah and Collin in 2018—admitted that if his estranged children were to accept, it would be their first introduction to Stephanie, who he popped the question to in November following three years of dating.
As he put it, "It'd be nice for her to meet my other kids."
"I just kind of support the kids that are integrated into the family," Jon continued. "If other ones wake up and realize what's going on, the door's always open here."
As for Hannah and Collin? They've already welcomed Stephanie into the family. In fact, the research analyst shared that Hannah had a heartwarming reaction to learning of the couple's recent engagement.
"Hannah loves me and I love her," Stephanie told Entertainment Tonight. "She has waited so long."
And Collin—who accused Kate of verbally and emotionally abusing him as a child, ultimately leading him to move in with his dad at age 14—echoed his sister's sentiment in a "special message" sent to the 37-year-old the day after Jon's proposal.
"The sentence was that I'm the glue," Stephanie recalled. "That resonated really well with me. So, he's very proud."
And while Jon didn't reveal whether he plans to invite Kate—who has since denied Collin's abuse allegations—to his nuptials as well, he previously shared that he hopes to improve his strained relationship with the matriarch, who he's become distanced from since their contentious 2009 divorce.
"I don't really have a friendship with Kate," he told E! News in April. "I mean, I haven't talked to her since 2018. But I think things kind of work themselves out in the future."
