Paris Hilton does Charity

"It's a great organization," Hilton told PEOPLE at Sunday's Life Rolls On Foundation's 4th annual Night By the Ocean auction. "It gives people hope and I'm really happy to be here to support Jesse."

The heiress bid on (and won) a $17, 500 surfing lesson with Billauer and Adam Sandler.

Although Hilton was recently seen frolicking in Malibu with new pal Tyler Atkins, 21, she claims she's all business. "I'm just focusing on doing a movie right now," she says. "It's a surprise but I start shooting next month."

"I was just at the Los Angeles Children's Hospital visiting all of the kids and premature babies in the cancer ward," she said Sunday. "I met with philanthropists and they're doing a summit with five major charities and we'll be doing stuff all over the world. I'm excited."
