KATY PERRY—EST. $330 MILLION

After finishing GED, Kate chose to leave school to pursue her music dream. She signed a contract with red hill records and released her first record “Katy Hudson”. Unfortunately, the sales volume was not good and did not attract much attention. After that, she signed a contract with Capitol Records in 2007 and released her single “I married a girl” to become a real celebrity.

Katy Perry, who was catapulted to fame after the release of her song I Kissed a Girl in 2008, actually started her singing career long before that. Fans of Perry might be interested to know that she released an album way back in 2001, seven years before she was telling us about how much she likes kissing girls. It was a gospel album (she was the daughter of Pentecostal pastors) that pretty much flew under everyone’s radar. To her credit, she’s been able to steadily work her way up from her small-town roots and become one of the hottest musical acts on the planet.
