ALright I am not sure of the credibility of this but, someone reported on wikipedia that katy's 5th single will be Fingerprints and the 6th and final will be If You Can Afford Me. Here is the link; http://en.wikipedia.org/wiki/One_of_...ty_Perry_album) go down to the section on singles when you get there. Idk if this is ture or not but idk we needed a katy thread.
Wiki is wrong once again. Why would they confirm two singles unless it was to different countries? Wiki also says "Breakin' Dishes" will be released next month.
A fifth single wouldn't be bad, but I wouldn't go further than that. The good choices would be "If You Can Afford Me" or "Mannequin." However, if she really feels like she needs to stop releasing singles, then "Waking Up In Vegas" was a good lead out single.
