While Perry is more widely known for her on-stage performance than her market performance, she's become a veritable businesswoman since taking the U.S. airwaves by storm about a decade ago.

Perry earned $33 million last year, according to Forbes, and has an even stronger 2018 teed up with endorsement deals inked for Procter & Gamble Co.-owned (PG) CoverGirl, Hennes & Mauritz-owned (HMRZF) H&M and a gig on "American Idol."
