Jon Gosselin and Kate Gosselin can officially put a one in front of the eight.
Here's some news that may make you feel old: The reality stars' six youngest kids Aaden, Collin, Joel, Alexis, Hannah, and Leah turned 18 years old on May 10. (Yes, you read that right!) And to celebrate the occasion, Jon shared a throwback photo of the sextuplets to Instagram Stories, writing, "Happy 18th birthday! Today is your birthday we gonna say it loud. I love you, Love Dad."
The former couple—who are also parents to 21-year-old twin daughters, Cara and Madelyn—welcomed their sextuplets in 2004, just three years before the premiere of their TLC series, Jon & Kate Plus 8. (The pair divorced in December 2009, one month after the network announced the cancellation of their show).
Although Kate and the rest of the family haven't posted on social media in honor of the big day just yet, Hannah revealed to InTouch Weekly that she recently had a "dream" birthday bash in Miami.
As Jon explained on The Dr. Oz Show in 2021, Hannah and Collin live with him while the rest of the sextuplets live with Kate. During the episode, Jon also revealed that he has not been in contact with his six other children.
"My dad got me a fancy Rolls Royce for the evening," Hannah told the outlet, adding that she "felt really special." She also noted that the only people missing from the celebration were her siblings, who were not in attendance. "I wish they could have been with me so we could all celebrate turning 18 together," she said. "I know they would be really proud of me."
Adding that she has "been literally counting down the days," until the big milestone, the Pennsylvania native also made it clear that she knows that not everything will necessarily change.
"Sadly, I think I'm still going to have the same house rules," she admitted. "But I am officially an adult!"

It's the show that started it all! Who remembers this cast photo for Jon and Kate Plus 8?
Back in October 2007, Jon and Kate Gosselin gathered their eight kids together for a trip to New York City. First stop? A visit to NBC's Today show.
"A precious Christmas memory. My 6 were 6. Christmas Eve 2010 and they're SO excited for Christmas!" Kate Gosselin wrote on Instagram with a throwback photo. "Look at those adorable smiles! #TheyAreMyHeart #My8ReasonsToKeepOnKeepingOn #NoMatterWhat #TrueLoveX8."
"I can't believe they're 13!" Kate Gosselin wrote on Instagram when celebrating a major birthday for her sextuplets.
Jon and Kate Plus 8 viewers loved when the family enjoyed trips together including a 2009 trip to the beach.
Rewind to 2014 when Kate and her children found themselves visiting Alaska.
Kate also treated her twin daughters Cara Gosselin and Mady Gosselin to a trip to New York City in 2014, where they stopped by the Manhattan Hotel.
"This was yesterday! Feels like school never ended...and they're already back! #SeniorYear #EighthGrade #ProudMom," Kate wrote on Instagram in 2018.
"My beautiful 'little girls' .... they keep reminding me how many days until they turn 14. Today it was '12 days til we turn 14, Mom.' HOW'S THAT EVEN POSSIBLE?!" Kate shared with her followers in 2018. "I told Leah that she's too small to turn 14. She said 'Yeah, true. Are you sure I'm not turning 11 or 12?' I'm positive. I gave birth to you. They'll always be my babies....I love them so very much!"
"Our big celebration of #15 is finally winding down here! We celebrated ALL DAY LONG, beginning with a present at 6:30 am before school! I'm so very thankful for my ‘babies'.... somehow they are 15 already?!" Kate wrote on the special milestone in 2019. "I'm amazed by them each day! I'm so proud of the positive qualities I've seen developing as they edge closer to adulthood."
"Happy 15th Birthday Hannah, Collin, Alexis, Aaden, Joel and Leah!!!! Wow I can't believe you are 15!!! Time is flying by!!!" Jon Gosselin shared on Instagram when posing with Hannah and Collin Gosselin. "I love you all very much. I wish you the best day ever and I hope you enjoy your birthday celebrations today and this weekend!!! Love always, Dad."
"Happy 18th birthday!" Jon wrote on Instagram in 2022. "Today is your birthday we gonna say it loud. I love you. Love, Dad."
