Paris Hilton: 'Harlow Madden is the Coolest Name Ever'

Paris Hilton is all set to be an auntie to pal Nicole Richie's newborn tot, Harlow Winter Kate Madden.

"I'm so excited!" she said at the Sundance Film Festival in Park City, Utah. "I've sent her all these presents. I'm going to spoil her!"

Though the 27-year-old party girl hasn't met Harlow - who was – born Jan. 12 to Richie and her Good Charlotte rocker beau Joel Madden – she is already a fan of her name.

"It's the coolest name ever," she told Us Weekly magazine. "I'm like, 'That is the coolest name, oh my God!' I wouldn't even think she would have thought of that. It's a beautiful name."

"Nicole is so into it," she said of the name Harlow. "She always knows what's cool before it happens."

Hilton - who was at  Sundance to promote her new movie, The Hottie and the Nottie – also opened up about troubled pop princess Britney Spears.

"She's such a sweet girl," Hilton said. "When I'm alone with her, she's a completely different person than they make her out to be. And I love her, I think she's very sweet and has a big heart."

"She's amazing," Hilton enthused. "I just want her to be happy. I think everything's going to be OK."
