Feel old yet? The toddler from the 2010s Disney Channel show "Good Luck Charlie" is now a teenager.

Mia Talerico, now 15, reunited with some of her former castmates in a recent YouTube video and viewers couldn't handle the cognitive dissonance.

"Good Luck Charlie" aired on the Disney Channel from 2010 to 2014. The comedy series followed an American couple, Amy and Bob Duncan, their three older children, PJ, Teddy, and Gabe, and their baby named Charlie. The couple had another baby named Toby later in the show as well. In the episodes, the second-oldest Duncan child, Teddy, played by Bridgit Mendler, made video diaries for Charlie to watch when she was older.

Charlie was played by Mia Talerico, who was 11 months old when she began filming for the show, according to her IMDb page, When the final episode of the show aired in 2014, Talerico would have been only five. She's now a ninth grader.

Talerico starred in a YouTube video posted on October 25 alongside two of her former castmates, Eric Allan Kramer, who played Bob, and Bradley Steven Perry, who played one of her older brothers.

The video was posted on Perry's YouTube channel as part of a cooking series he's been starring in since August, often featuring Kramer as a co-host.

In the YouTube video, Perry surprised Kramer with Talerico's visit. Perry said that it had been 10 years since Kramer last saw her.

"I'm so happy, I may actually, I may actually tear up here a little bit," Kramer said during the video after Perry explained the three former castmates would be cooking together.

A short clip from the YouTube video, which showed Talerico appearing to surprise Kramer, was uploaded on Perry's TikTok page, receiving 8.6 million views.

Users seemed touched by Kramer's emotional response to seeing Talerico, and excited about a reunion between the cast members.

Some commenters said that watching the reunion made them feel old, seemingly as a response to seeing Talerico as a teenager.

"Ive never felt so old and I can't imagine how Bob feels lol," read one top comment with over 60,000 likes.

"All grown up I loved watching good luck Charlie when I was younger ....I feel old," another user wrote.

When the clip was uploaded to Instagram, others chimed in, including a handful of Gen Z users, who would have been children or pre-teens when the show first aired in 2010.

"I'm only 20 and feel old," one user wrote, receiving 1,998 likes.
