Raise a glass to the Gosselin family, as their sextuplets have marked a major milestone.
The youngest of Kate Gosselin and ex Jon Gosselin's eight children—Hannah, Collin, Alexis, Aaden, Leah and Joel turned 21 May 10. On the same day, the matriarch shared pics of the latter four celebrating their birthday with her at a restaurant, including a photo of the group raising a toast at their booth.
"And just like that, they turned 21!" the Jon & Kate Plus 8 alum, 50, captioned her Instagram post, which also included an image of a chocolate-frosted cake decorated with gummy candies and other sweets. "Happy Birthday to my 6! #GosselinSextuplets."
Hannah, who has in recent years lived with Collin and Jon, celebrated her birthday with her dad and his fiancée Stephanie Lebo, who posted a video of the three sitting together at a bar on her Instagram Stories. Hannah and her dad are seen raising glasses of what appears to be dark beer.
Stephanie also shared video of herself and Hannah feeding each other gummy candies and then saying, "Cheers."
Collin, who has been estranged from his mom and most of his siblings other than Hannah for several years, is not seen in any of the images shared by his parents.
The 21-year-old, who has been keeping busy with his new power washing business, has also not posted any birthday-related content on his social media.
Last year, he expressed hope of a reconciliation with his estranged brothers and sisters. "I love my siblings very, very much," he explained to Entertainment Tonight in August 2024. "I think if we knew each other today, we’d be very good friends."
And Jon has said he would "definitely" invite Alexis, Aaden, Leah and Joel and twins Mady and Cara, 24, with whom he has also been estranged for years, to his and Stephanie's wedding.
"I would definitely send an invite to all of them," he told Entertainment Tonight in an interview published last December. "You know, they are my kids."
Look back at photos of Jon and Kate's eight children over the years.
