Perry is the latest in a long line of star hosts
US chart-topping singer Katy Perry has been announced as the host of the MTV Europe Music Awards.
Perry, who went to number one with her song I Kissed A Girl, will make her presenting debut at the ceremony in Liverpool on 6 November.
The singer is nominated for two awards, including best new act.
MTV organisers said they wanted the presenting role to be "much more informal and relaxed", and thought the 23-year-old would be "perfect".
Richard Godfrey, executive producer of the event, added that Perry would bring a "musical twist" to the job of host.
Music stars have been presenters of previous ceremonies, including Snoop Dogg, Tom Jones and Christina Aguilera.
Perry said that to follow in their footsteps was "an incredible honour".
"Do they know what they're getting themselves into? I just hope that I don't spill my cocktail!" she added.
Perry's chart-topper has sold five million copies around the world and is also in the running for most addictive track at the awards.
