The 34-year-old singer opened up about their wedding plans on Wednesday's episode of KISS Breakfast with Tom & Daisy.
"I did it! I got one! I got one," the "Firework" star quipped about nabbing her fiancé.
When asked if the two had already started getting ready for the wedding, Perry replied, "Well yeah, one step at a time."
"Definitely trying to, like, lay the good emotional foundation for the lifetime of commitment, which is, like, a big deal, you know?" she added.
Both stars also have a lot on their plate. Perry recently finished judging the most recent season of American Idol last month and just released her new single "Never Really Over" last week. The 42-year-old actor's new Amazon show, Carnival Row, also drops Aug. 30.
