Amazon are currently listing 'Teenage Dream: The Complete Confection' as coming out on March 13 in America, although none of the extra tracks have been named.
It's safe to assume that the various remixes and acoustic versions of the six singles will make an appearance, as will the leftover songs Perry and producer The-Dream returned to the studio to finish last October.
Talking about one of the new songs called 'Dressing Up', The-Dream said: "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."
