Katy says the reason Russell proposed so quickly after they started dating is because she's amazing in bed. She knows how to use those ta-tas!
"Like Ludacris rapped, 'I'm a lady in the street and a freak in the bed.' I can't rate myself, but if you ask Russell I'm sure he'd give me a ten out of ten," Katy told Now magazine.
And she's not worried about him losing interest and going back to his old ways either--as long as she keeps him busy in the bedroom.
"He's made no secret of what his life was like before me, but that's then and this is the future. He's cheated in the past but he knows how good he has it with me and I know he'd never do anything to jeopardize that. I trust him 100 percent."
So can we expect a Katy/Russell sex tape? They're such publicity whores, we wouldn't put it past them.
