Kelly Osbourne will host the MTV Video Music Awards (VMAs) pre-show coverage.

The former 'Fashion Police' star will present an hour-long show from the red carpet outside Los Angeles' Microsoft Theater alongside Sway and 'Girl Code Live' stars Carly Aquilino, Nessa Diab, and Nora ''Awkwafina'' Lum.

They will be joined by Nick Jonas, who will treat fans to a sneak peek of the music video for his song 'Levels', as well as performing the track for the first time.

He said: ''I'm thrilled to showcase my new single, 'Levels' at such an incredible night in music.

''There's nothing like playing new songs live for the first time, and I can't wait to surprise my fans during this performance.''

And as well as Nick, Walk The Moon will also perform on the red carpet.

They will open the pre-show special with their hit 'Shut Up and Dance', which is nominated for the Best Rock Video prize.

Following the pre-show, 'Wrecking Ball' singer Miley Cyrus will take over to host the main show.

The MTV VMAs pre-show airs on August 30 at 8pm, followed immediately afterwards by the main ceremony.
