Ten child actors traded braces and backpacks for red carpets, and the footage still stops people mid-scroll.

Every kid in Hollywood grows up eventually, but not every growth spurt gets caught on camera the way these did. TheThings Celebrity’s rundown, “10 Child Stars Who Grew Up To Be Beautiful,” tracks the glow-up of performers who started out on Nickelodeon sets, Disney soundstages, and family sitcoms before puberty and a stylist’s touch rewrote their public image. The names span three decades of kid TV and film, from ’90s sitcom staples to 2010s pop stars.

• Ariana Grande started as Cat Valentine on Nickelodeon’s “Victorious” and on Broadway in “13” before becoming a pop headliner.
• Demi Lovato’s earliest screen credit was “Barney & Friends,” years before Disney’s “Camp Rock” made her a teen star.
• Daniel Radcliffe grew up on camera across eight “Harry Potter” films, while Lindsay Lohan first broke through as the dual lead in “The Parent Trap.”

From Sitcom Kid to Leading Lady

Candace Cameron Bure is the textbook example the video leans on: she debuted as D.J. Tanner on “Full House” with the frizzy bangs an entire generation remembers, long before she became a familiar face in Hallmark movies and daytime talk. Abigail Breslin’s arc runs the other direction chronologically but hits the same beat — she earned an Oscar nomination for “Little Miss Sunshine” wearing oversized glasses and a deliberately awkward, pageant-obsessed persona, then spent her teens and twenties shedding that image for mainstream roles.

The throughline in both cases isn’t just better hair and makeup. It’s the gap between a character built for laughs or sympathy and the actor underneath it, which is exactly the kind of before-and-after that made That ’70s Show’s cast transformation such a durable clickbait staple in the same genre.

The Music Side of the List

Grande and Lovato anchor the pop half of the countdown, and their paths overlap more than casual fans might remember. Grande’s Nickelodeon run on “Victorious” came after stage work in “13,” while Lovato’s road ran through “Barney & Friends” straight into Disney Channel’s “Camp Rock” pipeline that also produced the Jonas Brothers’ breakout. Both spent their early teens performing for a kids’ network audience before adulthood, and a very different wardrobe department, turned them into cover-shoot regulars.

Big glasses, frizzy bangs, and a Broadway kid — that’s the “before” half of this list, and it’s not subtle.

Enduring Effectiveness of This Format

Then-and-now countdowns like this one thrive because the footage does the arguing for you — nobody needs convincing that Radcliffe at eleven and Radcliffe closing out “Deathly Hallows” are visibly different people. The same appetite for watching someone grow up on screen is what keeps pulling readers toward pieces like the Jason Momoa transformation timeline, where the gap between childhood photos and the adult star does most of the heavy lifting.

None of this is really about talent, and the video never pretends otherwise — it’s a straight puberty-and-styling countdown built around ten names everyone already recognizes. Bure and Breslin get the biggest “wait, that’s them?” reaction because their starting points, frizzy bangs on one, giant glasses on the other, were so specifically unglamorous by design.
