2010 Highlights: An impressive engagement ring in hand, Perry set to work on her follow-up to her 2008 breakthrough, One of the Boys, working again with pop maestros Dr. Luke and Max Martin while turning in one of the most memorable guest-judge spots in the early audition rounds of what would turn out to be a very lackluster season of "American Idol."
There was the inevitable pregnancy rumor to bat away, and then it was off to work on the "Smurfs" movie and complete the album, even as wedding plans continued apace. By March, Perry was calling Brand a "bridezilla" for his fascination with all things marital, and news leaked that pal Rihanna was planning Perry's bachelorette party.
