Katy Perry‘s Teenage Dream bestselling album is being re-released with new, never heard before material. Top producer Tricky Stewart said late last year that there were a lot of songs he wrote with Katy, that were really good, but just didn’t make it into the final cut. Now, with this new album about to be released, speculation is that most of their songs together will make it onto the disc. Stewart promises the new material will please fans, saying,it is going to be a “big record” that fits “right there in what her sensibilities are as a musician and a songwriter.” If this album leads to a 6th number in single, it will beat Michael Jackson‘s record, for having six #1 single on the charts from one album. The re-released album will be available on March 13, 2013.
