Paris Hilton and Cy Waits couldn't keep their hands off each other during an afternoon at the beach with her family in Maui yesterday. She put on a tiny bikini to play in the waves with her man after donning a unique cutout suit the day before. Her sister Nicky shared her own sweet PDA with longtime boyfriend David Katzenberg, and even the Hilton parents Rick and Kathy joined in on the love- and swimsuit-filled day. Nicky is currently off on her tropical vacation, but she recently shared her favorite LA spots with us, so check them out! The Hilton family are in Hawaii for Christmas and Paris has been happily twittering away about all their activities.
