Kate Gosselin’s sextuplets are 21.
The reality star celebrated her children‘s milestone birthday by sharing photos via Instagram from their restaurant dinner — but two of the six were noticeably absent.
“And just like that, they turned 21! Happy Birthday to my 6! 
#GosselinSextuplets,” she gushed to her followers.
In the social media upload, Kate, 50, was all smiles during a cheers moment with Alexis, Aaden, Leah and Joel.
The slideshow included another group shot as well as a sister selfie and a close-up look at the siblings’ cake.
The dessert was covered in frosting and gummy letters and numbers.
Hannah and Collin were missing from the carousel, as they have lived with their dad, Jon Gosselin, for years.
The DJ, 48, has yet to post about his kids’ birthday.
Jon and Kate welcomed their sextuplets in May 2004, with the little ones joining now-24-year-old twins Madelyn and Cara.
The former couple divorced in 2009 after a decade of marriage.
Kate went on to document her love life on “Kate Plus Date,” while Jon moved on with Colleen Conrad and then Stephanie Lebo.
He got engaged to the latter in November 2024.
Jon has had custody of Collin since 2018, with the discharged Marine since claiming his mom abused him — and Kate denying this and alleging her son had violent outbursts.
Hannah, for her part, moved in with Jon in 2016.
She made headlines last year for reuniting with her sister Leah, while Collin extended an “olive branch” to his siblings and is waiting to hear back.
As for his own estrangement from Alexis, Aaden, Leah, Joel, Madelyn and Cara, Jon spoke to “Entertainment Tonight” in 2023 about when they last talked.
He said, “I haven’t talked to Mady and Cara for, oh I don’t even know, over a decade. And then I haven’t talked to Joel, Aaden, Leah and Alexis for five years.
“At this point, they’re adults now. So, I mean, I don’t even know their phone numbers or stuff,” the former reality star continued at the time. “I’ve kind of just stuck with the kids that live here.”
