Toddler from ‘Good Luck Charlie’ reunites with castmates and people are feeling very old

Good Luck Charlie fans are flooding to social media in shock after seeing Mia Talerico all grown up.

Mia Talerico starred as the titular character in the hit Disney sitcom, starting filming at the tiny age of 11-months-old, according to her IMDB page.

The series first aired in 2010, which doesn't seem that long ago - until you catch a glimpse of what Talerico looks like now that is.

Good Luck Charlie centres around the Duncan family and takes the format of a video diary by Charlie's (Talerico) elder sister, Teddy (Bridgit Mendler), preparing Charlie for her journey to becoming a grown-up.

The sitcom aired from 2010 until 2014 and subsequently documents Talerico changing from an 11-month old baby to a five-year-old.

So, if Talerico was five, nearly six, in 2014 and we're now in 2023 - well, you can do the math.

Bradley Steven Perry, who played the role of Gabe Duncan - Charlie's brother - in the series, hosts a cooking series on his YouTube channel, accompanied by Eric Allan Kramer - who played Charlie's dad, Bob Duncan.

In an episode uploaded 25 October, he took the opportunity to reunite some of his Good Luck Charlie co-stars, surprising Kramer by bringing a now-15-year-old Talerico along.

The video shows Perry explaining they have a 'special guest' on the show.

"This person has four Michelin stars, well-known on television, still very well known - this is your genuine reaction I just want the camera to know - [...] You know this person better than they know you. This person, actually, barely knows who you are. This person also gets referred to as someone in your family," he teases.

Talerico then walks out into a kitchen where Kramer is stood, her on-screen dad's eyes wide and mouth open in shock as he realises who she is.

He exclaims: "Oh my god. Oh my god. Oh my god. How are you? How can you look like this when you're only four?!"

Prepare to start checking your head for grey hairs:

Perry shared several clips from the episode to his TikTok too, the clip of the surprise with the caption: "Woah time flies."

And fans of the show are almost just as taken aback as Kramer, seeing Talerico all grown-up a stark reminder of just how long ago they watched the show and subsequently how old they now feel.

One user said: "Ive never felt so old and I can't imagine how Bob feels lol."

"His eyes tearing up, you know he means it," another commented.

A third wrote: "Wow she's so grown now this is so sweet."

And a fourth added: "THE REUNION WE NEEDED."
