She might seem all sweet and perky, but pop star Katy Perry has clearly taken some of Russell Brand's influence on board.

Perry is stepping into Brand's shoes to host the MTV Europe Awards today and told reporters: "We're stepping on each other's turfs. I've learnt a couple of things over the last months that might not be appropriate for this!"

Katy insisted that her fearless attitude was part of her appeal.

"I'm just going to be myself. MTV asked me back because I have this no fear attitude," she explained.

"I don't care if I do fall over or if a boob does fall out!"

And she really does mean that, folks. The singer went on to say that there would be a very real possibility of "nip slips', as she put it, and added: "I'm highlighting what God gave me. Using what your mama made!"

But how will she beat the 10 costume changes she managed last year?

"There's a 1930's dark romantic vibe. It's still gonna be fun but the fruit has all gone sour," said Perry.

"It's sexy with naughtier undertones. Taking the vibe of Berlin and putting into the visual – using lots of crystals and bowler hats and bow ties and boobie things."

We're guessing the "boobie things" might have been Russell's suggestion.

Whether by accident or not, it's not difficult to find celebrity flashers...
