She became famous for being a party-hopping teen, but now Paris Hilton is all grown up. The heiress, who turns 30 on February 17, is a bit apprehensive about reaching one of life’s biggest milestones. “It’s scary,” she told In Touch at the NBC Golden Globes party in Beverly Hills on January 16. But in true Paris style, her fear won’t prevent the social butterfly from celebrating in style. “We’re planning a lot of big parties around it. I’m so excited!” she added. Will the big 3-0 bring big changes in her life — like marriage and a baby? “Yeah definitely! I’d love that,” Paris, who is dating Las Vegas club mogul Cy Waits, said.
