Paris Hilton and her sister Nicky Hilton party it up in Cannes at the Chopard party with some guys, one of which looks to be quite enamoured with Paris.  Is this a new man in her life?

In a couple of the pictures, it looks like Paris is serenading her sister.  The two look to be having a great time.

Paris recently appealed to her Twitter audience to help a little boy who is battling cancer and needs bone marrow. You can find the details here.
