Demi Lovato was just 10 years old when she was cast in wildly popular children's TV show "Barney and Friends", one of several youngsters who danced and sang alongside a large purple dinosaur. Little Lovato became fast friends with another child in the cast, fellow child actor Selena Gomez, whose career followed a similar path to pop stardom via Disney.

The budding young actress landed roles in such TV series "Prison Break" and "Just Jordan" before landing the lead in the 2007 Disney Channel film "As the Bell Rings". This led to a starring role in Disney Channel's hit series "Sonny With a Chance", which spawned the short-lived spinoff "So Random".
If "Sonny With a Chance" was a success, it was nothing compared to her next Disney Channel project: 2007's "Camp Rock", in which she co-starred alongside The Jonas Brothers. The made-for-TV movie musical spawned a sequel, with Lovato confirming in 2018 she'll be appearing in the upcoming (and R-rated!) "Camp Rock 3".

Lovato's 2008 debut studio album was an out-of-the-box hit, earning her both commercial and critical success, ultimately selling a half-million copies. The success of "Don't Forget" paved the way from her transition from Disney star to a bona fide pop sensation.
After a brief hiatus from music (Lovato had her hands full with "Camp Rock 2" and "So Random"), she returned with 2011's "Unbroken", which featured the mega-hit "Skyscraper" and cemented her as a star to be reckoned with on the pop music scene.

As her fame grew, so too did Lovato's openness, candidly discussing her struggles with mental illness, substance abuse and being victimized by bullies. She used her celebrity to bring attention to all these issues in a variety of ways, including launching an anti-bullying campaign and aligning herself with the annual We Day celebrations (she's shown here appearing at We Day 2012 in Vancouver).

In 2012, Lovato was tapped to be a judge on "The X Factor", a huge hit for Simon Cowell in Britain that was launched in the U.S. on Fox after Cowell left "American Idol". Along with Cowell, Lovato sat on the judging panel with music exec L.A. Reid and fellow pop star Britney Spears. The show ran for three seasons.

During her stint on "The X Factor", Lovato's dual talents as a singer and actress were utilized when she guest-starred in a multi-episode story arc on the fifth season of "Glee". Lovato played a NYC waitress who hooks up Kurt (Chris Colfer), Rachel (Lea Michele) and Santana (Naya Rivera) as part of their band, Pamela Lansbury.
