Sitcom success

In 2009, Demi was given a sitcom on Disney Channel titled 'Sonny With A Chance', firmly putting her alongside contemporaries Miley Cyrus, who starred in 'Hannah Montana', and Selena Gomez, who led the cast of 'Wizards of Waverly Place'.

But she was unable to continue with her role as the teenager who lands a role on a TV comedy series as she suffered from mental health issues.

She said at the time: "It made sense for me to go ahead and leave the show to focus on my music.

"It's kind of sad for me that a chapter of my life has ended but there couldn't be a better time for me to move on.

"I don't think going back to 'Sonny' would be healthy for my recovery. Being in front of a camera would make me nervous."
