The Hot Chick (2002)

Jessica Spencer is the hottest, most popular girl in high school. Jessica, her best friend April, and a couple of other hot girls Lulu and Keecia visit the mall to hang out and do some shopping. They enter a new age store, where they check out a pair of ancient earrings. Unbeknownst to Jessica, these are magical ones set in ancient Abyssinia.

A princess known as Princess Nawa is disgusted by the groom of her arranged marriage and switches bodies with a slave girl by means of an enchanted set of earrings. Since the earrings are not for sale, Jessica steals them. But the next morning she gets a big dose of reality when she wakes up in the body of a 30-something lowlife male, Clive, a career criminal. Clive finds himself in Jessica's body. Now it's up to Jessica (in Clive's body) to find a way to get her body back, while Clive (in Jessica's body) takes advantage of his new body to set in motion a crime spree to put the blame on Jessica!
