Katy Perry’s on to the next leg of her European promotional tour for her newly-released CD, Teenage Dreams. We caught up with her in London as she was arriving at the ITV Studios. Just prior, Katy tweeted “On my way to see me favorite Queen… Alan Carr… And THIS JUST IN: Paul O’Grady is gonna be there as well! So me favorite Queen(s)!!!”

Perry’s been getting all sorts of good news lately. Teenage Dream debuted in the number one spot on Billboard’s charts, and rumor has it Simon Cowell has tapped Katy to be one of the judges on the U.S. version of X-Factor. For a whopping $340,000 a show, no less.
