Hilton was photographed hugging and kissing Waits after the sports car was delivered to her driveway.

And the socialite followed it up by staging her first 30th birthday bash - on Tuesday night she was joined by 300 friends, including rapper Lil Wayne, comedienne Kathy Griffin, and sister Nicky, at a 1920s-themed party in the Hollywood Hills.

The heiress wore a red basque and feathery skirt for the Pimps and Showgirls party, and told her followers on Twitter.com: "So amazing when Lil Wayne stopped by to give me a birthday present. Everyone at the party loved seeing him!"

Hilton looks set to continue the celebrations in style - earlier this month (Feb11) she revealed she is planning a series of parties to mark the big day, saying, "It's a big birthday so I'm going to be going to a lot of places to have parties: Los Angeles, New York, Las Vegas."
