"Katy and I went into [the studio] just to address some issues with records that we had done in the past that didn't end up going on Teenage Dream,"
"So we are in the process of just listening and freshening up things and getting ready for something special she has going on."
He also revealed a title of one song that Katy's is currently working on:
"This song is really special. It's called 'Dressing Up,' so it's going to be a big record, I think," he said. "It definitely fits. It's right there in what her sensibilities are as a musician and a songwriter. She doesn't change much. She has a very keen musical taste. It'll be really good."
