Paris Hilton seems to be holding true to promises she made during and just after her incarceration. The heiress made an appearance at charity auction over the weekend to help raise funds. Or, at least, to be seen. The Life Rolls On event was complete with an auction, where Hilton won a $17,500 surfing lesson with Billauer and Adam Sandler. At the event, Hilton told reporters that she was focused on her next movie – a “surprise.” Paris further said she’d start shooting next month on the flick. Hilton has also recently visited a children’s hospital in an effort to continue with her charitable dedication.
