Socialite Paris Hilton's promise to do more charity work following her release from jail is being carried out - the socialite has started work helping to raise funds for children with spinal cord injuries.

She was at Life Rolls On Foundation's 4th annual Night By the Ocean auction on Sunday in aid of her close friend Jesse Billauer - a former professional surfer who founded the charity after he was paralysed.

The Simple Life star paid $17,500 for a surfing lesson with Billauer and Adam Sandler.

She said later, "It's a great organisation. It gives people hope and I'm really happy to be here to support Jesse."

And Hilton's charitable nature doesn't stop there, adding, "I was just at the Los Angeles Children's Hospital visiting all of the kids and premature babies in the cancer ward.

"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."

Hilton was released from Lynwood, California's Century Regional Detention Center last month after being jailed for violating her probation from a 2006 drink driving arrest.
