Demi Lovato has been named as this year's host of the Teen Choice Awards.

The singer will present the annual star-studded event on July 22.

The former Disney star's career is going from strength to strength after she was revealed as a new judge on the latest season of the US X Factor earlier this year.

"Fresh off of news of her X Factor gig, Demi Lovato is set to host this year's Teen Choice Awards on July 22. The singer and former Disney star will join Cat Deeley and others for the live show on Fox," reports EW.

The Teen Choice Awards celebrate the year's biggest achievements in music, film, television, sports, fashion, comedy and online.

They attract the entertainment industry's brightest stars and have previously been hosted by the likes of Katy Perry, Miley Cyrus and Jessica Simpson.

This year's line-up of performers includes No Doubt, Flo Rida, Justin Bieber and Carly Rae Jepsen amongst others.

Zooey Deschanel, Lea Michele, Taylor Swift, Josh Hutcherson, Zac Efron, Ellen DeGeneres and Gordon Ramsay are just a few of the stars scheduled to attend the event.
