Does anyone know if Dressin' up will be the second single of the new album of katy perry?

with a music video for it? when possible will be to download the new version of the song that I've listened to the preview? and then doesn't anyone know when the " part of me" video comes out? thanks a lot to all Rumor has it that Dressin Up will be the next single and final single of the TD/TCC era. The full song will probably be available to purchase by the 26 of March. Insiders said that the "Part of Me" Music Video will be released next week. Hope this help. :)
