It reportedly took hotel heiress Paris Hilton only two hours to drop a cool $100,000 in Beverly Hills, Calif.

Hilton, 22, stuffed her car with goods from Louis Vuitton, Sony Style and Jennifer Kaufman during a Saturday shopping spree, the New York Post reported Monday.

She reportedly left the shopping district once her car was so stuffed it couldn't hold another bag, the newspaper said.

Despite her $28 million trust fund, Hilton has turned out to be a savvy businesswoman, the Post noted.

In addition to her reality TV show "The Simple Life," Hilton has been acting in films, recording an album, has her own clothing and perfume lines, owns a club in Orlando, Fla., and has written a best-seller, "Confessions of an Heiress."
