Clear the roads! Paris Hilton is coming through.

The hotel heiress, 30, treated herself to a brand new 2012 California Spyder Ferrari worth $300,000. The red sports car was delivered to her L.A. home just before noon Friday.

"When Paris walked in all of our eyes were on her," a source from the Ferrari dealership tells X17. "Ferrari is excited that she has purchased one of our cars. We know it's going to bring worldwide exposure, and Paris is the perfect fit for our brand."

Hilton waited to take her new ride out for a spin until Saturday, telling her Twitter followers: "Just drove my new car for the first time. Such a beautiful car and so much fun to drive! I love it!"

In addition to her new Ferrari, Hilton has a fleet of cars that includes two Bentleys, a Lexus LFA, a hybrid Escalade and a Range Rover.
