Katy Perry: Lock up your boyfriends

The PVC-wearing singer said has signed a deal with lingerie company Victoria's Secret, meaning that the costumes for her forthcoming world tour will leave little to the imagination.

She told The Sun: 'Victoria's Secret are on board so girlfriends - lock up your boyfriends. That's the thing with me, I think a lot of the girlfriends are bringing their boyfriends and they're not really dragging their feet. They will secretly be excited, I think.”

And the 26-year-old said she has a few other tricks up her sleeve for the show.

'It'll be really fun, very visual and, like I said, engaging all the senses,” she said. “We're looking into alternative stuff, like a couple of companies who are helping us make the aroma of what you kind of smell on the CD. Perhaps Snoop [Dogg] will make a guest appearance - if he happens to be in the city at the same time then why not? The boyfriends will enjoy that.'
