GOOD Luck Charlie child star Bradley Steven Perry is unrecognisable 12 years on from his Disney debut.

Bradley, who was just 11-years-old when he played the mischievous Gabe Duncan, the third of five siblings in the Duncan family.

The TV star, now 23-years-old, regularly shares snaps on social media with his fans and it's clear the actor has done a lot of growing up.

Looking miles apart from his character on the Disney Channel, Bradley has shared snaps of him graduating, photos with his nephew and a series of him looking dapper in a suit at various events.

The talented actor has given fans a glimpse inside his life - from holidays to spending time with friends and attending events.

When the actor isn't sporting suits for celebrity outings, he's shows off his impressive physique in topless snaps.

Premiering in 2010, Bradley joined alongside fellow Disney veterans Jason Dolley and Bridgit Mendler. 

In 2011, Perry landed a co-starring role in the Disney Channel original movie Sharpay's Fabulous Adventure opposite Ashley Tisdale.

In the film, Perry played Roger Elliston III, a precocious young dog owner and Sharpay's rival, competing to get his dog a starring role on Broadway.

In 2008, Bradley landed his first role at the age of 10 in films Choose Connor, and Magnificent Max.

The following year, he made his television debut with a guest-starring role on the CBS crime-drama Without a Trace.

Over the next year, Bradley continued to appear in small roles in The Goods: Live Hard, Sell Hard, Opposite Day, and Old Dogs.

Bradley is not the only member from the Duncan family that has changed dramatically since their time on the show.

Child star Mia Talerico played adorable Charlie Duncan - but the youngster looks very different since her Disney debut.

While her big sister Teddy (Bridgit Mendler) was the narrator on the hit American sitcom, Mia definitely developed her own following.

She has shared snaps from holidays to spending time with her cute guinea pig and attending glamourous events.

After four seasons, the show came to a bittersweet end in 2014. 

The show focused on the Duncan family of Denver as they adjust to the births of their fourth and fifth children, Charlotte "Charlie" and Toby (Logan Moreau).

In each episode, Teddy Duncan adds to a video diary that contains advice for Charlie about their family and life as a teenager.

Teddy tries to show Charlie what she might go through when she is older for future reference.

Each video diary ends with Teddy or another family member, saying the eponymous phrase, "Good luck, Charlie".
