There's no way she only recorded 14 songs for the album.
12 Album tracks
+ Dressing Up
+ Part of Me
+ Work It (Writers: Katy, Cathy Dennis, Greg Wells, Cuomo Rivers)
+ Milk Milk Lemonade
+ Rihanna Collab Demo (This one's a bit shakey, but I assume Rihanna hear some sort of demo when she said it was brilliant.)
At the very least. If you all remember there was a load of fuss made over Katy working with Cuomo Rivers back when Teenage Dream was being recorded, so I assume Work It was a Teenage Dream recording. Pretty sure Katy mentioned MML as well in a tweet/interview/etc in late 2009?
Even if it isn't a TD song, I NEED it. Cathy + Katy? Yes please.
