15 Celebrity Kids You Can’t Accept Are All Grown Up Now

8. Haley Joel Osment

Haley Joel Osment is actually older than me, but I still think of him as my little brother who sees dead people. So seeing recent pictures of him makes me feel like we were separated for ten years and then found each other.

9. Jamie Lynn Spears

Aww, Britney Spears’ little sister is a little mini-me. How adorable. What’s that? She has a five-year-old daughter? WHYYY.

10. Maddox Jolie-Pitt

Angelina Jolie delivered a lovely speech last month at the Governors Awards, but all I could focus on was how old Maddox looked sitting in the audience next to Brad Pitt. Didn’t Angie just adopt him?

11-12. Kendall and Kylie Jenner

There was so much hope for these two mini-Kardashians when their reality show first premiered. But then they got older and Kris Jenner took them in her evil clutches. And now it’s all cleavage and fakelationships.

13. Nolan Gould

Is it just me, or did Luke Dunphy on Modern Family suddenly age like ten years over the summer? The new season premiered this fall and it was like I was looking at a different person.

14. Daryl Sabara

This is what the little kid from Spy Kids looks like now. He’s 21. Absorb that information, take a deep breath, and try not to lose your grip on reality.

15. Mackenzie Rosman

Who’s that up there? Just 23-year-old Ruthie Camden from 7th Heaven posing for Maxim in her underwear. Reverend Camden would be so ashamed.
